Are you saying that even if "almost all of us" agreed cruelty is not good that, since "the judgment is ultimately individual," cruelty in this case is "good" ?
No. I'm saying that the person who inflicted the cruelty judges his actions to be good (although that does not have to be the case...he may judge his actions to be evil but choose to do them anyway), while other judge for themselves whether or not his actions are good.
What is your view of what God might be? It ain't easy to put in words, is it?
