I feel that one of the biggest problems with our world today is that we have decided that there is not evil in the world. That is wrong.
When my niece was five and her brother three, their mom said the boy not to do something. He did it anyway. The mom told the boy that he was being bad. My niece told her mom he wasn't bad, he was misguided.
That's good for a five year old, not an adult.
Denial of evil allows evil to flourish.
