Question: If you could “plant ideas” in Chris’s head that easily, then how come trolls tried for years to make him get a job and move out etc. with absolutely zero results.
Because it's one thing to plant an idea, it's another thing to change behavior.
Back when Bob was the #1 Idea Guy in Chris's life, he planted a lot of great and not-so-great ideas in Chris' head. Putting aside the homophobia, racism, etc. which was more or less an artifact of Bob's time growing up in the south, OG Chris' ideas were to have a more or less wholesome relationship. If it weren't for the internet exposing degenerate trash to Chris he probably would still be wanting these things.
When people tried to plant ideas like getting a job, taking a shower, etc. Chris seemed to genuinely want to change.
The problem is that these are all just IDEAS and Chris is incapable of actually following through on these things because he simply can't perform any actions that don't bring immediate gratification. He drew Sonichu because he enjoyed it, and when he didn't enjoy it he couldn't even follow through on commissions that people were PAYING him for.
The most effort Chris has *ever* put into anything that didn't make him feel good while he was doing it was driving to Cleveland to rescue Julie, an unprecedented and still not-repeated 24 hours of delay of gratification, because I'm sure he fully expected to make love to his heartsweet once he rescued her.
I'm sure Chris could have been an exceptionally hard worker if hooked up to some sort of automatic skinner box that fed him rewards for doing productive things, but we don't live in a world like that. It would probably help greatly with less-retarded autists as well -- they could probably cure cancer hooked up like this.
Well-meaning trolls never succeeded in manipulating Chris into bettering himself because they couldn't change that core aspect. The only success was ever achieved in manipulating Chris into doing or saying something that either gave him immediate gratification or offered him reprieve from immediate pain. Bella did no different. This is made VERY clear when Bella failed to tempt Chris away from fucking Barb -- an immediate gratification -- with the delayed gratification of fucking Fiona. If Fiona had been *right there* and ready to get it on, Chris could have been easily swayed, and if Fiona had stayed there Chris would have never even thought about fucking Barb again unless Fiona went away on a 2 week trip or something.
