There are many people that want to be and choose to be the villain.
It is not that they have a difference of opinion of what they consider good and evil. They just want to be the bad guy.
Because they will do what they want, hurt or kill whoever and break and destroy peoples lives because that is what they want to do and they feel they can.
I am around people like this on a daily basis. This is not my opinion, this is a fact.
