Jabber as a yandere would be very,,,,confused. If he kills someone he sees it as doing zanka a favor. zanka shouldn’t waste his time on people when he could instead be getting stronger. he would be a very yuno gasai kind of yandere. there’s no point in paying attention to other people when all he needs is him. Why does zanka need to prove himself to other people? They just don’t see the potential in him like jabber does. Which is why they’re perfect. jabbers the only person who understands him so he’s the only person who deserves him. He’s just like him after all.
However with zanka as a yandere, I feel like he would be more of a yamai ren type. he knows very well that it’s wrong, but what is he supposed to do? Jabbar is an idiot who keeps getting himself into trouble, he needs protecting. even if he never asked for it. jabber need someone to look out for him, because nobody else does it. And of course when he murders people it’s because they waste jabbers time,sorta similar to how jabber views others wasting zankas time. just a little different. The way that zanka sees it jabber shouldn’t fight people who do nothing but give him the bare minimum. jabber need someone strong. Hence why he’s the best for him. He’s the one who got him to bare his soul after all,no one else.
tdlr:
Jabber kills because he wants zanka to pay attention to him and him only
Zanka kills because he wants to be the only one there for jabber
sorta the same but slightly different
