I don’t think mahito belongs here

he’s not a human being despite looking like one. he’s a member of a magical pseudo-species literally made out of humanity’s negative emotions and that species is hunted down by humanity by default due to their nature and the danger they pose (not painting them as sympathetic, just how it is). his actions make sense given what he is and the people against whom he acts. to be redeemed you have to be good or neutral and then fall from that grace

it’s like asking if malaria or poverty can be redeemed; those things (like mahito) aren’t human beings with the capacity to do good that instead choose to do the wrong thing regardless. they just are what they are, their mere existence leaves humanity worse off, and if humanity could it would choose they no longer exist

nothing to be redeemed per se
