It's not like believing in god guarantees you passage in heaven anyway, basically every single thing humans do is a sin and you would be turned down. If god was so great and benevolent he'd let everyone 'good' into heaven regardless of whether they believe or not. Besides, the whole concept of heaven & hell is nonsense. Religion is useful for governments because it keeps the peons opressed. If they believe in an afterlife, then they won't look for a better life while they are in a bad situation. (I.e. Revolutionary Russia (Stalin))
