Personally I wish humankind had invented or discovered another way in which to come to terms with its own mortality. Not saying I have the alternative answer, but I wish there were one. In world history, its not that long ago we were burning "witches" in the name of god. Religion today is used to oppress peoples, especially women in a way that does not sit well with me, and still used as justification for many conflicts.
As to the question , will we roast in hell? , no we will not, because it does not exist. It was invented by people who wanted others to behave and act in their preferred way.
Again, must say, I do respect other peoples religious choices. I come from a staunch Catholic background, and know how important it can be to people.
