Depends who you ask, how many Christians said "heaven" but completely forgot the OTHER 30,000 or so denominations that would completely object to your perceived entitlement? How many Christians here thought they'd be going to heaven simply because they followed the Christian faith, neglecting the fact that it's just as likely that Allah, Vishnu or Zeus could decide what happens to you postmortem?
I believe neither heaven nor hell, but to be honest you're playing against infinity here, nobody knows because there's an infinite amount of possible deities that haven't even been thought up yet. What if your fate was decided by Cthulu, Yog-Sothoth of Gandalf?
Seriously, you have no idea and the sooner you face up to that fact the sooner you can stop being so damn judgmental.
