>>30677930I feel singled out by that spoiler, haha. To be fair, if you assume he was physically abused by his dad, it would make sense for him to then turn around and abuse others. That's generally how the cycle goes. Especially when it's hinted that he finally snapped and beat his dad back, it suggest he's got poor control over his aggressive tendencies and/or uses violence to cope (bent golf clubs, destroyed furniture in the mansion, etc).
Seeking approval of authority figures is also a way of coping with abuse, i.e. Stockholm Syndrome. So really you could go either way, but the former just seems to make more sense to me.
