Excerpt from a book I love ..
"Here's what I think. You are a good person. You're made of good materials. That's just a fact. A scientist would say its in your cells, that it's built into your DNA just like the color of your eyes. Wherever it comes from, just being you is being good.
I don't mean you can't make mistakes like the rest of us. But you're luckier than the rest of us because if you just do what feels the most like you, you'll be fine. And forget about evil. There's just no way."
