He fully admitted he hates those 'darn laws' about girls being underage. Just because he's scrawny or pathetic or a mangy harmless twit to us doesn't mean he cannot overpower a child. He takes great pleasure in harming animals that have no possible way of defending themselves against him. Lots of criminals look harmless or fragile and we don't take them seriously until they take action. I'm not saying Jay is going to go on a rampage and kidnap a ton of children, but I do know he is extremely adamant on pretending he is not interested in children when he clearly is, and he's just too stupid to understand how dangerous that is for him for the world to know.
To him it doesn't matter how far he goes because he will deny it with all evidence pointing to him, anyway.
The thing with Jay is - and this is taking from what had been written on his own Steam userpage - he's all about
empowerment. He
revels in being able to lord power over everything, to have the power to do as he pleases and not have to follow the rules set by others if they don't ultimately serve his own goals in the end. Part of the reason why GK is so fixated on the PPG thing, I think, is that it was running when he was in grade school (I think he's about the same age as me and admittedly I liked the show despite worrying about it being too girly an influence on me, oh the irony given who Craig McCracken married off of that show) and what he saw were three
kindergarteners who had super powers that at any point could just up and leave whatever task an adult figure wanted them to do (and the only times when the adult was not ultimately repentant for forcing the girls to not go save the city was if a silly moral was involved or if the girls themselves were not in total agreement, I.E. the bath episode where Buttercup refused to bathe to the point monsters feared
her smell exponentially more than they feared
actually fighting her) so they could stop the baddie of the week with their superpowers and tear up half the city with nobody giving a shit so long as the
PPG did the damage.
I think a good gauge of how the show really does reflect on GK's morality is the episode where HIM literally just sends the girls on a wild goose chase using vague words and riddles and that if they don't get to the Prof in time, he's gonna pay...and even though the PPG literally beat up a guy to make him cry and damage public property out the wazoo, the only consequence of them
failing is HIM making the Prof pay...full price for what the Prof claims were crappy pancakes before taking his daughters to the diner across the street, which distresses HIM for some reason as he doesn't seem to legit want to do anything more than run a diner, yet because he's normally a bad guy, that's somehow worse than the PPG getting off scott free for beating the shit out of innocents. TL;DR - heroes can terrorize a town and its populace and
even still be defeated by the bad guy, but because they're heroes that's okay, whereas
anything the bad guy does as a result of defeating the heroes is downright criminal even if it's something as silly as a bet over a discounted price of a breakfast that either outcome was still going to have the Prof. pay money for shit food because HIM literally didn't do anything
remotely illegal the whole episode. This moral immunity of the heroes and implied damnation of the baddies is, naturally, rampant in all of Jay's stuff.
And for Blossom herself being his waifu? I think GK just has a thing for redheads, though whether or not this is
why he's fixated on Blossom, or if his love of the character is the source for his desired dream warrior amazon slut submissive caretaker wife having red hair. I can't even remember if he's ever
drawn a girl that didn't have red or reddish-brown hair.
Hell, even the show has a source for his abusive opinion on animals. For the most part, animals do
not fare well in this show, as with the exception of squirrels who Bubbles occasionally enlists as a hit squad for assistance (she can talk to them obviously), there is a good amount of punishment dealt to animals for no real reason. Mojo Jojo? Yeah, he's kind of a dick and karma has been kicking his ass for years since he's the one who unintentionally made his nemesis trio, but he also gets his fair share of abuse
outside of when he's evil (anything to do with that Anubis bust
usually ends up with him being the victim of a prison rape joke - seriously). Fuzzy Lumpkins? It's never really established what he
is, much less why he occasionally comes to town to stir up trouble only to eventually get his ass beaten down. The talking dog? He's the choice damsel in distress for instant crisis moments that the show even lampshaded it when a visiting superhero (who was a fraud) is shown
literally kicking him into traffic just to look good when said dog is saved by the "hero" at the last second.
Now that I think about it...PPG is actually kind of fucked up in what kind of abuse is being dealt to just about anybody that is swept under the rug if the girls are the ones doing the abuse.
