Is it rude to get annoyed when people think you are nice?

Let me break this down for you: If you're not a nice person, you are NOT a good person. If you are a nice person, YOU ARE A GOOD PERSON. You can't be both, which means you can't be good and evil at the same time. If I get into a car and run over somebody, I'm bad/insane (not able to empathize, etc.). If I get into a car and immediately slam on my brakes, because I'm about to hit somebody, I'm good/nice/and I have empathy/sanity, etc. Understand? Being means "is" My name is... I am... His brain is... His heart is... "Be nice" means the teacher/adult, etc. knows you have it in you to be nice to others. If they thought you were not nice or that you were insane, they would get you help. Nice or evil is in the heart. It is not taught behavior. It is the first reaction (jolting forward without thinking, etc., regardless of what others are doing) after seeing a person calling for help, a person getting hurt by another, a person needing help, etc.
