Mostly I don't meet rotten people, but this doesn't mean they are good by nature. People change their initial responses. If you think someone is good by nature, as if he/she doesn't get mad or jealous or aggressive, then that person is not a human being. Haven't you had the experience that you felt so annoyed from someone, but then you did something else that was more acceptable than being aggressive and violent because it brings a more favorable result? OK, search the Internet when some police departments went on strike and see what happened. I think humans are good as long as there are consequences to their behaviors. Why do you think there are governments and law enforcement forces and religions if people are "good" by nature??!!!!! People killed each others on a football (soccer) game, for God's sake!!! You just deny the human nature. We aren't divine. "Good by nature" is not an accurate statement. Also watch babies how they act and behave. We teach them to be good because the outcome is more favorable. Otherwise, leave them to their nature and let's see the goodness in them!!
