Excluding the usual obsessesiveness, for what other reasons did you get into yanderes

I'll go first. The main reason I got into yanderes was because I thought it'll be a kids free zone. No hate but everytime you read a story, 90% of them have kids, whether it be in epilogue or in the main story. Kid haters like me really have nowhere to go. So I thought that since yanderes are supposed to be epitome of possessiveness, they might get jealous of their kid too and hence refuse to have kids. Unfortunately for me, I didn't realize how many yanderes have a breeding kink. But even tho I came for another reason, I stayed bcs of the same obsessesive love so I guess its a win-win for me.
