Is he an ENTJ or unhealthy ENFJ?

I (ENTP) met my friend's (who's an INTP) brother (his type I'm not sure is an ENFJ or ENTJ but I met him about 5 or 6 years ago through my friend) and he seemed like a fine guy at first. But I'm not sure what type he is. He mostly talks about how logical he is and answers "What's the logic to this" to every question even a movie. And he sometimes tries to act like a Thinker type which him crossing his arms a lot and questioning people a lot and trying to look imitating. He often clashes and argues about a lot of stuff to a point where it can get out of hand and hard to control. In the past, he was more angry and would lose his shit or temper or very minor things like if someone tripped on his charger (when he charged it in the middle of the kitchen table) and scream in the guys face over it. One time, he'd get mad when someone called American Food "Western Food" it got from him calling the guy Ignorant to throwing stuff on him and flipping him off in anger. Whenever he'd argue with someone, he'd counter with "Why are you attacking me" or "Why are you showing bias right now". He can get involved in other people having a little arguing trying to act diplomatic and the refeee but often makes it worse. Whenever someone in annoyance says something, he stops him and says "What do you mean by that" and keeps on repeating the same thing not knowing it's pissing the other guy off even more. He's gotten much better since then. One time, he'd ask my friend if he "commited this crime" would he defend him. Apparently the crime was very bad so the friend said I couldn't back up any one who would do something like that and that offended him and said "It was a test if he'd show loyalty" or something. He also gets overly defensive a lot and often tries to make himself look like a victim. He also overdramatics a lot.
