Can the christian (or muslim for that matter) doctrine of hell

[kryptic]

ever be justified?
I have a friend who started to attend a pentecostal church a couple of years ago. Some of the stuff that comes out of his mouth is frankly alarming.
We got talking the other day about the afterlife (which I dont believe in) and he seems to think that it is perfectly justifiable that I will spend my eternity in hell because I dont believe in God. (at least not in the religious sense). I have lost a fair few loved ones over the years, all good people but not religious, and he seems to think that its justified in some way to believe that these folk are burning in a fiery lake. If it wasnt for the fact that I believe he has been brainwashed (and the fact that we have been friends a long time) I might be tempted to clock him one when he comes out with stuff like this.
Any thoughts on hell or on how to deal with this kind of indoctrination?

Sorry, last post was supposed to be for another question on a different thread.
