Lmao, of course this pathetic doormat would want to heal them. Yeah, who cares about attempted murder? MC won so they're not at fault at all, right? Awful writing.
God there is no logical in world conclusions to this kind of manga. Bloodless violence. No broken bones. No accidental deaths. No actual punishment. Big ass spells thrown with clear indication with intent to kill but no one in the residential area adjacent notices. He shouldn't heal them. And if he does he should leverage it. Weak mc.
