Psychopaths are like Jeffrey Dahmer. Their whole emotional reward/punishment system is fucked, so they don’t feel weird or bad about killing animals, or drilling holes in people’s heads to try to make them into fuck-zombies.
Sociopaths are like.. think compulsive liar. Lots of abusive/manipulative bullshit, constant passive-aggressive gamesmanship. I personally think Ralph is not so much a full on sociopath, but just someone who is driven crazy by how much work it takes to distract from self loathing. All the shit he puts outward is a cope and an excuse not to clean his own ass up. Throw on the drugs and booze, and it can LOOK like a sociopath at times, but trust me. Doesn’t reach the bar.
Psychopathy and sociopathy are both like forms of retardation, not superpowers. They don’t in any way dictate how smart people who suffer from them are. This is why I say Ralph doesn’t fit the bill. Like ok, he’s retarded, but you can see how he put himself in that position over time. He’s the result of a sequence of wiggering and self esteem so low he can’t even see himself as anything else, that doubled down every time it lead to a setback. Ralph COULD be fixed if he could give up the substance abuse long enough to suffer the consequences of his own emotional reactions to his own behavior.
