why good people do bad things

In my book, Center Field, Mike is usually a good person but then a nerd named Alex got on his nerves and they got in a fight. Alex got suspended and might be kicked off his varsity baseball team. He made a bad decision but it doesn’t make him a bad person. He has to do community service and might miss the first game. He is also fighting for center field and from his decision, might not get it. Clearly, the moral of this story is to think about the consequences of your action before you do that action.
