No I’m sorry for the last part but Minato wasn’t left with his mother’s dead corps. Their mother turned insane and wanted to hit Minato with a vase because she blamed him for the divorce. Itsuki was there and stopped the vase and that broke his left arm. Then the mother left the house blaming Itsuki and Minato for betraying her and others bad words. And the day after, she hung in front of the school in the middle of the town. But Minato wasn’t left with the corpse. But it’s true he was often with his mother who wasn’t very stable and always told him he looked like her. That’s what scared the most Minato because even now his big fear is to turn into a jealous and mad person like her mother was.
I wanna defend Minato's side, honestly. Or let's say I'm biased on his side. I saw a comment about his abandonment issue. But its not all that. He still blames himself and always thinks that he's the reason why his mom unalived herself. He always thinks before that if he hadn't told her mom what he saw that one time , her mom wouldn't let go of that little piece of sanity she had. As to why until now he has difficulty of telling someone what he really felt. And remember that he was left alone with his d3ad mother for weeks until his big brother found him.
