If you believe in life after death (redux) ....

Evil is a natural point of human life. The only perfect being is God, mankind isn't going to be perfect, mankind was created to have free will, and that includes the free will to choose to commit evil acts, including a lot of ones we tell ourselves aren't evil because we like to think we're better than we are. As much as we like to set people apart, these are good people, these are bastards, the truth is everybody has the ability to do horrible things, a lot of them just choose not to. You can't look at half the $@(% people commit and say evil doesn't exist, and you can't compare their behavior to animals' instincts and say that it's a natural evolutionary trait. Animals kill but not for the reasons nor with the depraved methods that people do. There is no way any animal tearing another's throat out or mauling another animal to death can be compared to a man breaking into someone's home and in the middle of attacking them, injects them with bleach to increase their suffering, or a man who puts weed killer in his wife's food and pretends he loves her so much while her whole insides are burning to the point of blistering, or a Japanese Imperialist soldier raping a Chinese girl to death with a bayonet and then photographing her corpse with the weapon sticking out of her genitals, or a Croatian death camp guard sawing a prisoner's head off or slamming a child's head into the wall so hard pieces of his skull break apart. Like it or not, those are all choices people made for their own sick satisfaction, they could just as easily never done those things, nothing compelled them to.
