Clearly, this makes a lot of assumptions, and Rosa outlines a lot of them in the post. First, it assumes that God and Satan are actually real.
Second, it assumes that Satan is able to act as his own agent and that he has freewill. According to Christian teaching, he presumably does have freewill since he disobeyed God and revolted against him. Third, it assumes that God is either unwilling or unable to squash his great nemesis. Finally, the question assumes that Satan is an able creator in his own right. For instance, he can create false gods to lure humans away from Yahweh, he can create false impressions in people’s minds and he can create feelings of hate and contempt in the hearts of potential believers in an attempt to draw them away from the fold.
OK, with those assumptions on the table, since Satan has all this power, why doesn’t he create a place that rivals heaven as a great postmortem destination? Why doesn’t Satan create a hell that can compete in the afterlife free market of ideas. It could be the Key West of the afterlife; heaven without all the groveling and singing. Instead of all the weeping and woe and fire and brimstone that has given hell a bad rap for hundreds of years, Satan could create a hell that’s actually better than heaven, with waterfalls, mermaids, no illness or loss of life, sex without the threat of pregnancy or AIDS, endless buffets, wine and beer on tap 24-7 and perfect weather.
That would make one hell of a spiritual travel brochure.
