I don't single out crimes by religious people as worse as those from others either. I only mentionned it to say that the're no better or worse than the rest of us.
When it comes to the hell doctrine, well, at least when it comes to the Christian faith it all depends on what the bible says about it, don't it? If you claim to be "a true Christian" you can't go, "Ok, I like this part, so I'll believe it, but I don't believe this part because I don't like it." As far as I'm concerned you either believe all of it or none of it.
Problem is that most Christians really haven't got a clue about what's in the bible. At the most they are familiar with certain parts of it. Time has erased most of what I've read from my mind, but in my younger days I've read quite a bit of it, including the prophecies - Daniel and Revelations especially, the last of which is incomprehensible to most because they can't make heads or tails of the symbolism in the book. But with the help of some books I've managed to plow my way through it and I've learned that all the syumbols that are in the bible are actually explained in the bible itself. In other words, "the bible always explains itself."
Anyway, to cut a long (and no doubt boring
) story short, Revelation is about the evils of world religions, the false prophet, the anti-Christ, how you'll be able to recognoze him when he arrives on the scene (the famous 666 number of the beast), how this figure who is actually a representation of Satan will deceive the world into thinking that he's God, the return of Christ after a 3 1/2 year rule of this anti-Christ figure, predictions of plagues, wars, earthquakes and much, much more. Fascinating stuff, and things that most of those that call themselves Christians are totally unaware off.
