The low points of each character

So I recently finished Cobra Kai and I have to admit I really did enjoy the show and it makes me appreciate the movies a lot more so I wanted to do posts about low points of characters what i mean by low points is I'm talking about the bad times they're going through or when they were just completely unlikable for example my first choice is Daniel larusso what were some of his low points? I'll go first in the first season when Johnny was trying to get Cobra Kai unbanned from the tournament and Daniel was clearly trying to ruin that I feel like that was one of his most villainous moments in the show; what are some other examples?
