God has made human beings in his image, as his icon in creation. For God to torment such divine representatives forever and ever in hell seems akin an act of perpetual divine indirect self-mutilation. Is that an unfair thought? It may well be unfair so please just say so if you think it is. It is just a rough thought.
I guess the more substantive issue underlying the thought concerns whether God would ever abandon his icons to everlasting damnation. It is very hard to imagine that God would desire to forever abandon creatures of that nature. So what would cause him to do so? Indeed, what would cause him to do so so quickly and easily (i.e., at death)? Would he not put up more of a fight before forsaking his images forever?
I do not believe that God would ever abandon such a creature. God did not create trash and he will not trash what he creates.
