Look every good story needs someone to cheer on and someone to boo. Without both the story would not be as good.
Sure Ryker is an asshole who punched a woman in the face because she crashed his car and not because she hit 3 of his so called friends. He says he is doing horrible things, most of which we don't have any proof is true. What if what Charles said was true and Ryker is just messing around with the MC. Sure we know he wanted to talk to the MC and he went about it in a horrible way, and he was creeping on Stacy (For that he should be punished). Yes we know he treats women as sex objects and not people, and he hit Wendy. He was not in a proper state of mind which does not give him any excuses, but it does make me question some of his actions. What if it was all just a way to haze him for joining the team, most sports and schools do that still even though they are not supposed too. Yes his actions at the bowling alley was way too far, but everything else could just be a creepy guy who is hazing the rookie to the team.
I know it's just another stupid thought by your neighborhood Loco Gringo, but what if it was a hazing that just went wrong and not some evil plot.
