Is it okay to yume the Prototype (Poppy playtime)??

I REALLY like it but im just a little worried because its tehnically a child that got experimented on and turned into the Prototype (kind of like fnaf animatronics but to a more severe degree).

I wouldn't say that it acts childishly considering how sadistic, manipulative and intelligent it is, along with it being in it's 30's(?) by the time we meet it ingame (it was most likely created in 1989 ...)

I'm not really into Poppy Playtime so im not sure if there's some extra lore that says that he didnt age mentally or something, so... help??

(sorry for the sloppy english lol its not my native language)
