@KOOK13 It’s a pity story, relax a little bit. There are two sides of the coin. Yes he is an insufferable ass but it’s more than likely that not that he was raised without love just like her. This may not mean much to you but for others, maybe you can give him some slack. Billy goes to school, billy gets jumped by bullies, billy goes home, Billy’s little brother wants to play, billy starts acting rash at little brother, since and repeat, billy becomes a bully. This is that father but instead he is neglected and then neglects his kids.
Also I’d like to add that at leased he is doing something to change rather than be the same. It’s not like if you were given the choice, you’d become the villain on purpose (unless your brain is wired that way)
It’s more than likely his family had him taught to stay neutral and not to involve himself with others too.
