He doesn't care about his family and wife just want to be the number 1 hero, such a trashed father.

Endeavor has been abusing his kids since their youth. But Shinjuro has only started after he succumbed to depression

Like they both made pretty big mistakes and are kinda of taking consecuences of it, but the fact that a abuser of not only his kids but the entire family is most worst than a father that was good until her wife dead happend and didnt know how to process it

I can understand rengoku dad we see him before as he was in Despair and In a depression state that no one knew how to help him in, all of a sudden now his son died of course he's grieving and his way of grieving is an alcohol. Everyone needs therapy

The man forced his kid to train so hard and his kid would burn his self with his quirk and he made his 5 year old son train for the entire childhood.
