Is it a red flag if a man gets drunk and yells at you?

A guy I'm dating ate an edible from a friend that he didn't know had mushrooms in it. He had a few beers on an empty stomach after work and had a weird anger spell where he thought I told him to shut up when I didn't say a word and was weird and angry. So angry. He pulled out his hair at one point. He apologized for it later and even stopped drinking more than one beer every few nights (his idea not mine). Should I give him another chance or run? I told him we are friends only until further notice but I have a gut feeling he's bad news.
