-People are injured
-People die and families are affected by the losses
-No one deserves to be injured and/or die

-The causes of war and violence are vacuous
I'll provide examples
Violence:
-9/11 in the USA: Very tragic day. No one deserved to die
-The Holocaust: No one deserved to be tortured and/or die because of a man's racism
-Europeans coming to the Americas (present day Canada, USA, Central America, and South America): They didn't care about the Natives that were there before them. So, they killed and conquered rudely
-Slavery in the Western Hemisphere
-USA dropping two nuclear bombs on Japan (that was BRUTAL). Innocent people died
-Etc
Wars:
-The Vietnam War
-World War II
-The Cold War between Russia and the USA
-World War I
-Wars before World War I
-The Iraq War
-The one in Libya
-Other wars before 1900
-Other wars I didn't mention
I wish people were serene. People need to think what they're going to do. If they don't think, there will be HARSH ramifications. Those ramifications are injured people, dead people, affected families, etcetera. The ONLY time war and/or violence should be acceptable is to defend yourself, ONLY if you didn't start it. The parties starting wars and violence should be ashamed of themselves.
