Comments of chapter undefined of Divine Emperor of Death

Maybe I didn't get something right but some stupid logic he have here, even if that women didn't try to kill him(and she didn't do it only because of the suposed ''master" behind him) she still tried to make him a slave and taking in account the experience of his previous live(that part mentioned in his inner demon chapter) he surely should hate slavery much more that murder, so why the **** he still want to spare that fucking reincarnated *****? It's just stupid considering how he was furious when his other girlfriend was injuried
