I know it's for some kind of drama, but you know you can still have drama with characters saying how they ACTUALLY FEEL. Hell, that might actually create more of an interpersonal dilemma between them. Making a character say all those bad things just makes them look like a bad person and makes them unlikable for absolutely no reason. The situation is not as dire as his harsh words so it just looks like he's hurting his feelings for no reason basically. The only time this sort of temporary “I hate you” works is when the other characters' life is on the line and they need to get away from the 1st character as quickly as possible. The problem is bigger than the sacrifice, so it balances out and seems reasonable. Sigh, it's just too dramatic for what it is.
I'll give my answer too!!
