It doesn't have to be that way. People can have the capacity for violence but choose not to. I think that's better than being incapable of it in the first place.

Your issue is that not everyone shares that mentality. And when so many people reach a point that they then refuse to fight, a tyrant attacks. There are so many sources- beings in which violence has dug its roots- that Existence is cursed with their presence forever.
