The Potential of Evil in Human Nature

Everybody has the potential to Be very evil. So you could have sprouts of that I'm thinking about in those later star wars movies where the guy is killing Han Solo his dad Spoiler and says thank you. But it can be thwarted something like that corruption is not going to be a fundamental tendency, but it is a possibility that can happen, right? There's only one theory would be well. We have these two Internal tendencies one towards good and one towards evil and then we could cultivate one or the other.
