My brother has a bad temper recently and is very impatient with me and my brother. He also hit my brother yesterday. Has he gone bad? Do this to your family.

I think your brother has a bad temper recently, he is impatient with you and your brother, and he also hit his brother. This shows that he has recently encountered something particularly unsatisfactory at work. Does he have a girlfriend? If you have a girlfriend, then you may have trouble with your girlfriend. Because you said that his temper has only recently become violent, your brother should not be bad, but he is in trouble.
