These guys were hostile towards players. I'll give you an example. I rolled a 1 on an attack against a goblin that was fleeing. The DM decided that a 1 meant I accidentally hit another player who was not even close to the goblin. He made me roll to see if I overcame the players AC and I rolled a 20, which he said meant I crit the other player. Then he had me roll for damage and I rolled max damage and killed the other player. It was that player's first time playing and they had spent a ton of time creating their character. That was when I decided I didn't want to play with that DM any more. Deciding I hit another player all the way across the room was hostile, and then forcing a crit was icing on the cake. Actually having me outright kill another player when I was attacking a goblin with eldridtch blast is just ridiculous.
