What is good and what is evil? Who decides that saving a baby from drowning is good, but putting him in a microwave is evil? It's all about perception. To me it is more than simply knowing it is wrong and evil to use hacks or nuke a baby or do something wrong. I actually experience a physical gut wrench when i see things that go against my being. That tells me it is wrong and evil, to me.
But someone else couldn't two shits if a animal was tortured or someone blew up america. To them it is not right or wrong, it just is.
Like I said, everyone has it in them to be "evil" or "good". I just think it depends on where you are, who you are and who raised you.
Most would agree that shooting someone dead is wrong and "evil". But say that person is threatening your life or your wife or child, is it now suddenly not evil to kill him? See how quickly we can justify our actions to suit our needs? As I said, it's all perspective. How many Germans were killed during WWII in combat? Soldiers and civilians alike? Nobody called the Allies evil, so why are Osama's men evil because they killed 5000+ people om 9/11? They are also merely waging war on their sworn enemies and doing what they believe is just and right.
Please, I'm simply trying to prove that what is evil and what is good is merely in the eye of the beholder.
