after having watched this video
I decided to write a comment to that video that I'm copy/paste here below to share it with you readers of HA forum.

Hi, you have a great sense of morality young man. I enjoyed listening to your arguments because they make much sense if someone uses own good inner sense of morality (not poisoned by the surrounding culture) and applies it to the "mainstream" Christian theology. Following your same arguments, many years ago, when I was as young as you, I was very near to becoming an atheist because if I have to choose to believe in a God with highly questionable morality, or in no God at all, I'd rather chose the latter.
But... I tell you what... after much experience in life, and much reading, and studying and pondering... I found out that isn't God immoral.... but it's the mainstream theology that uses wrong arguments and turns out giving a picture of God as an immoral being.
The idea that every man deserve punishment due to original sin, which was committed by their far far far very first ancherstors Eve and Adam, is immoral itself. Human justice (at least in the so called "civilized" world) doesn't punish the children for the crimes commited by their parents; it would be an unaccettaple injustice if that would happen. So, if human justice doesn't do that, how can we believe that an all loving and all just being as God is told to be, could be less just than the human justice?
Doesn't make any sense.
Also, as you well said, not only mankind is supposedly deserving God punishment due to the "crime" committed by their ancestors thousands and thousands generations earlier, but the delivery of such UNJUST punishment is allegedly waived due to the punishment delivered to a single innocent man which is said is even more innocent than any innocent man as he's not affected by the so called "original sin/crime". That's also immoral (to punish an innocent because of the crimes committed by others) and it doesn't make any sense; not in terms of equity (because the amount of punishment delivered to the innocent is likely near to almost zero compared to the amount of punishment waived, so why not waive it all and spare the innocent?) not in terms of logic (if God is only tied to His own will, why if He wants to be merciful to mankind, he still needs to deliver a punishment to an innocent?).
But... then, one day, I finally conceived (partially inspired by the writes of S. Freud, Emmanuel Swedenborg and CS Lewis) the solution to the mistery that can put together a loving God, an original sin, and the sacrifice of God's begotten son himself.
First of all, if there's anything to understand out of the reading of "The book of Job" (included in the Bible) is that suffer IS NOT a punishment from God... God doesn't make people suffer to punish them... indeed punishment isn't something that viable for an all loving being.
Secondly, the great mistakes that do all religions is to think of God as a man, a "father", therefore as authority BEFORE than love... while God, by definition of "all loving", is likely more like a woman, a "mother", therefore as LOVE BEFORE authority.
So, what is the original sin? and why it's passed from generation to generation? and what the original sin caused? and why there's need of sacrifice to repair the damage caused by the original sin? Here are the answers.
The original sin, IS NOT, as they all teach you, the disobey to God's authority which therefore would cause God to deliver a punishment... the original sin is THE LOSS OF TRUST on God's love. Such loss of trust (due to Satan deception and free will) has caused the mankind to detach itself from God's love, and that's why end up living in a Godless earthly realm where there's suffer... not as punishment but as consequence of losing the love connection with God.
Because such trust and love can't be easily recovered in a Godless world, all the generations that came after, which didn't know God, had also suffered.
So why Jesus, God's begotten son, has incarnated on earth? and why he sacrificed himself not just his earthly life (that is not much valuable after all) but bearing one of the most terrible torture ever conceived by men?
Because Jesus has come with a message which is the WAY to restore our trust in God an our love for God through Jesus.
So, it's NOT Jesus resurrection or His death that SAVEs, but His message (His WORD) and His WAY (so, it's the WORD that can save us from the eternal void once we die. The VOID is what expects who can't love God, because outside God there's only the void in the spiritual transcendent dimension, or there's the immanent universe, which is where we experience our earthly lives).
But WHY Jesus had to suffer that much? why so much sacrifice in terms of terrible PAIN? why He HAD TO go through that?
The answer relies on the mystery of suffer, love and free will.
God loves us, He wants us to love him back, but can't force us to love him/her... love is such only if it's a free choice of heart. So God's love doesn't allow Him to do anything which may violate our free will... to interfere in our lives with His direct manifestation, which wouldn't make us love him, but rather be submitted to Him (notice that the word "Islam" means "submission").
So... how can an all mighty God prevent Him/Herself to interfere in the life of those who He/She loves. What can prevent the love of a mother to run to her loved son that she miss so much?
Suffer... only the suffer of the loved can stop the loving one.
So, this is my theological theory, if God tries to alter the laws of nature in any way and interfere in our world, that will cause us MORE suffer (in addition to the suffer already caused by men and by the earthly life). God made our universe in this way so to protect us, to protect our free will, from His wish to interfere. God's love doesn't want us to suffer (more than we already do) so God can't interfere in our world. God CAN do everything, but because of being concerned of our suffer and our free will, God's love stop Him from using his power. In other words, it's NOT that suffer exists as a punishment because God is immoral and doesn't love us or God isn't powerful enough to prevent suffer, it exists for a number of reasons, and one of those reasons is that it's a "device" that can even stop God from interfering with our free will.
But there's an exception... if a man bear the suffer and voluntarily OFFERs such suffer to God, then God is allowed, for the amount of such suffer, to do MIRACLES in this world (many Godly men, saints, have been through a great amount of suffer that they voluntarily chose to bear because of their love for Jesus and God).
Now, we all know that Jesus has become so popular because of His many miracles, not because of His army (like in the case of Islam and it's prophet), but those miracles (including His own resurrection... see how the Shroud of Turin, the burial cloth of Jesus, defies all known natural phenomena) have required and caused the violation of laws of nature, therefore a great amount of suffer had to be VOLUNTARILY offered to God, in order to make them possible. So, thanks to Jesus sacrifice, He had been empowered to defy the laws of nature, to show signs to the people of that time, that made them to believe him without doubt and made them to love him because His sacrifice was also the proof of His love for us. And through the love of Jesus, many people had found the way to trust God's love and find their way back to Him/Her, to salvation, and eternal life and joy.
Therefore Jesus sacrifice IS NOT, a punishment that has been delivered to Him instead of to the sinners, so that the sinners can be waived from receive the punishment. Jesus suffer is what has been needed for Him to be able to deliver His WORD to the whole mankind (and provide us a WAY to God/heaven) and in a way that men have still full complete free will if to BELIEVE and TRUST in God's love or not.
Thank you Jesus.
I love you Jesus

Amen
