I don't believe there is such thing as "evil". Even when I was religious, I didn't believe in the concept of hell. Of course I believe in terrible upbringings, selfish greed, and ignorance leading to terrible actions. But I believe even the most horrible people the world has ever seen has a perfectly good explanation behind it. If not, then it's probably due to a mental illness. I know this might not make a ton of sense, but I just have a hard time believing a innocent baby can grow up to do evil acts without there being some circumstances that lead to that behavior. I am NOT justifying any behavior or asking for any lenience in punishment for these people. But seeing them as "evil" doesn't help us solve the problems that lead to the things we despise the most.
