Sometimes people find it difficult to fathom why anyone can be a godless person in this lovely world of ours with its myriad of gods to choose from. Often its due to the assuredness of people who claim exclusivity to a truth and damn all else who does not subscribe to that truth.
Trying to look at this from a neutral angle, I think even the staunchest Christian would have to admit how obnoxious and downright callous it is to suggest that an omnipotent, loving God, would strike down a teenager for any reason. Perhaps I am giving Christians too much credit.
