The majority of readers lack emotional maturity as well.
As for JJK, isn't not rage or anger. It's just plan aggression. When he feels joy and excitement (as we see when he wins), he's aggressive. When his upset or hurt (when he confronted Dan about the spray) he was calm, but other times was aggression.
With Dan, he's "all bark, no bite". Noticed he never hit Dan like the first guy? Or every other guy (excluding his coach)?
When you are overestimulated, you get aggressive sometimes. For him it's just what he knows. Though, I see him getting humbled and taking it step by step. (▰˘◡˘▰)
Still don't trust him. Gotta beg on his knees to our dan baby to return. Also the reason why the fandom hates him so much is because he lacks "emotional maturity". Like bro is an empty shell that only knows rage.
