you get it!!! and yeah the unrestricted internet access as a child was a fun thing ngl tho for me it wasnt yan sim but creeoypasta fics which were often wayyy to graphic xd (ah ill never forget that one jason the toymaker fic where he put a toy mouse in some guy's mouth and made it explode it was fun stuff for a 12 years old to read ngl xd) tho those guys at least were created on their own and almost all of them had reason why they're like that so they weren't empty shells
oh i absolutely love ray tho it is a pity we cant get good ending after learning he gets powers from people he kills (especially considering he was literally raised like that it wasnt exactly his choice and i think mc had the right to know that) as for nulla i have yet to do his route so cant say (i did septem and have not opened the game since ^^;) as for my example keith and tenebris from duality which has the very interesting concept of the player being able to get a bad ending by making keith or tenebris get even more yandere than they already are plus they both have personalities and interests outside of mc and both have good reasons to be as yandere as they are tenebris bc of his genreal heatred of humanity bc fae and the fact that very few humans dont run they moment they learn about him so he is not loosing mc and keith who grew up with tenebris and is therefore desintised to violence and death plus they fact that so many lovers left him already and he is desperate to have and keep a lover
also ngl i love that we're writing an entire essay on yanderes uner your update post xd
