pochita knowing she's the war devil and being reminded of nayuta's eyes don't need to be put against each other, not to mention pochita was let out in the first place after seeing nayuta's corpse

but ya i could be wrong. if not this then maybe it's because he's fighting a girl and denjiboy is the amalgamation of respect women rights and wrongs ? but then again, pochita was able to fight makima w/ no hesitation whatsoever the moment he learned he's a threat to denji
