or damned you to for eternity if you did repent. This is mentioned in the Gospels, but often overlooked.
I don't buy into any afterlife, but understand that it may calm down people who look to a god to bring justice where there has been none on earth. It's more hope of hell for others than fear of hell for oneself that drives some people.
In the West, Judaism was the root for Christianity and Islam, so it's always a good idea to see what Jews have to say about this. Turns out that over the years they've had a lot to say, and not so clearly. It seems that it all started with gehenna which is not a place of torment, but purification, and is essentially being apart from God.
From there, they were exposed to Greek and other concepts of the afterlife, eventually leading to modern day confusion over the whole thing. Pretty much where the rest of us are.
One reason I became a Quaker years ago was because of their view of Hell-- since no one has managed to come back from the dead and tell us what happens, we are free to some extent to make up our own minds. And we will find out eventually.
