Would he actually get in trouble with the law regarding the "theft" of trash and its usage in his perversions? I mean, it's definitely some degenerate stuff but I'm not sure it's actually illegal. Setting up a hidden camera in the toilet on the other hand...
If the pervert is someone you like theres no problem at all
I'm not sure she's at a stage where she actually likes him.
The difference here is that he's not impacting her with his creepiness. Unlike the other creeps who swarm over her, and therefore are dangerous to her, he's only being creepy indirectly. Maybe her radar has detected he's a super extra virgin. And so, his disgusting actions are seen as hilariously pathetic that can be observed for entertainment rather than something that could actually lead to harm for her.
But yeah, maybe she indeed has some interest in him and so has ended up seeing his perverted actions as cute.
We're on this train wreck now so we'll just have to enjoy the big crash that's coming.
