disagreements to death

Honestly, people die over stupid things like in the cruciple almost every day. Which is really sad. It also seems like in every single movie, someone dies. So death is everywhere when it comes to altercations with people.
For example, in almost every single super hero movie, someone dies. No matter who it is. Like in all the Spider-man movies, he kills the green goblins, venom, and all those other people. In this case, killing them is actually good because they will just hurt more people. This example helps me see why the people in salem kill the people supposedly following satan. Not saying that the death penalty is right.
But,real life isnt like that unfortunately. For example, when people have a "negro moment", It usually either results in death or maybe jail. Just like how the cryps and the bloods have been killing each other for a really long time. This really is unnecesarry deaths because this whole war is pointless. Just like how killing people without actual proof is pointless.
So my point is that death is a part of almost every really serious altercation because if you make a person mad enough. Or you do something that will harm you or people around you,they more than likely will get rid of you. In many cases, this is death.
