I agree. Plus, Shirayuki didn't go from himself killing ppl. They deserved it. Seeing how they bullied the gurls, the teacher znd the boys. They r so disgusting. They had no remorse. They even raped that gurl and molested Haruki. They deserved death. But no death made me satisfied i wanted them to be bitten to a pulpe before getting killed. Agh .I'm annoyed by them till even after their death. As for the fatty teacher she deserved it too. In fzct who didn't deserve Shirayki.s death again !! No one
Because he is really safe when he's with Shirayuki. I know Shirayuki is batshit crazy but who wouldn't be if they are hurting the one he loves? I'd rather Haruki pick Shirayuki out of all those psychos, with enough love and care he can actually be a decent person plus the psycho tendencies but Haruki can surely handle that..

All these other psychos are helping Shirayuki look better to Haruki, in a twisted way. Like, sure, Shirayuki is also a psycho but he doesn't actively hurt Haruki physically.
If I were in Haruki's shoes, I would totally be manipulated into thinking I was only safe with Shirayuki by my side.
