Ghost Rider(s) went to Heaven to kick the archangel Zadikal's ass out of Heaven after he dethrowned God from it. I don't see how going to Heaven would be offensive. However Hell is a more intresesting place. Did you ever read Dante's the divine comedy? The trilogy is broken into 3 books: Inferno, Purgatory, and Paradice. Inferno (Hell) is the most populare and compelling of the 3 books. I guess that's why Marvel (and everybody else) seems to put there charaters there. I also think it be very hard to convince a person to leave Heaven.
