You set up your poll wrong; it currently requires 7 answers selected to unlock the "Vote" button, and I presume you didn't intend that you can only leave one answer unselected.
Mine are Pride and Sloth.
One thing you did miss about Pride is that unrepentant yandere must reject society's mores, which is typically considered prideful/arrogant - "the world condemned me, but it didn't matter, because I believed I was right and the world was wrong".
I think it's the "votes per user" set at 7 that's doing it - the poll requires exactly that number of answers, which is why it didn't let you have 7 votes per user with only 7 options (since that would only have one valid vote i.e. "everything").
I don't think the forum software allows a variable number of options selected per vote, although I could be wrong.
Oops, I thought I already wrote my response to this. Here to rectify that.
All of the sins fit me but if we're going for centering on me as a yandere, greed fits best. You know the idea of hungry ghosts? They're so hungry. They have huge gluttonous stomachs and tiny throats. So they can only fit so much in their mouth at a time, always leaving their cavernous bellies sorely empty. I am like that. I always want more. More love, more more more. I am never satiated.
