And that's the defining thing about demonization: Logically, you can grasp these concepts, but the lack of a soul makes you unable to not only really get them but also to actually care.
Tollus, tho, he still has his soul, which leaves him able to do all that but choosing not to care.
I mean, it's a hypothetical argument, but if it's possible to reinject a soul into a demon, being able to suddenly feel and "understand" the repercussions of the actions one took as a demon might drive a person into deep depression or worse.
Well, that's how I see it, anyways.
Not to mention, one is a bald, scrawny male bastard, the other a thicc, feminine sex idol. It was never going to be fair.
