i think he does have a soul if he didnt why would he feel remorse its just a logical stand point of feeling right and wrong i guess animals dont do this because they only have a spirit but not a soul but doomsday is an intelligent being that now does know right from wrong ever since he became smart but what good would the hellfire and stuff do if he just came back? He would then be imune to it and that would be major suckville for the magic users of the universe but then again i dont know if he can grow an imunity to magic if he can to cosmic power like the GL ring as if heard why not magic.
so then the question is raised -- cana soul be developed as intelligence evolves, or is the soul a birthright -- ie -- does it come with being born?
hmmmm
regardless, the problem i have with the soulfire is it causes pain, that's all. penence stare wouldn't likely do much as all dd has done has been in his nature so he wouldn't know remorse as most do.
i'd say dd in this rather interesting match up . . .
