First of all behaviour is not usually made plural. Bad behaviour that makes one hated by others is in my opinion is rudeness and impoliteness. Politness is trying to make other people around you comfortable. Consider other people's feelings and needs act appropriately.

Hi, So soory. Bye

I agree with Johnz regarding the two mentioned behavior that can cause hatred among people. However, I would like to add another negative behavior which I personally abhor. And that is arrogance! In my opinion, arrogant people don't care about others' feelings and they tend to be rude, impolite, sarcastic and boastful.

I think judgmentalism - if you assume the worst of people, i'm sure they often assume the worst of you. It is best to give people 'the benefit of the doubt'. Also, not to feel aggrieved about bad things that happen to you - often, it is not the person's intention, so it is best to 'forgive and forget'.
