its a social media addiction plus crippling insecurities. i dont know the scientific term for it but he has that personality where he absolutely cannot be embarassed or humiliated. seems like NPD is more about needing praise all the time. ralph gives himself all the praise he needs. if it were about praise, he would have figure out a way to impress more than the dozen or so KS fans that white knight him in chat and on twitter. he would have slowly implemented some kind of change to his personality that would garner more approval and admiration. ralph's brain is just trying to navigate a minefield of embarassment and humiliation.
so yeah its going to get waaaayyyy darker. especially now that his gunt guards are taking turns dunking on him. even if its more playful, and he's definitely going to play it off with people like jim because of the humiliation he can cause him amongst the people who still simp for ralph, deep down its going to burn him inside. and he can't really go at gator that hard because gator is so buddy buddy with jim. unless he just comes to terms with his life and starts being a decent person, the spiral may never end.
