well....yeah, those labels are biased towards Christianity cause, well, Hell is a Christian thing
It's srot of difficult to get into the difference between absence of God now and in the state of Hell, but let's just say that the ways in which it is possible to shut yourself off from God now are nothing compared to the state of being eternally shut off.
The Christian writer Thomas Merton writes the metaphor, "Hell is where no one has anytrhing in commonwith anybody else except the fact that they all hate one another and cannot get away from one another and from themselves." and "[It] is not so much that they hate what they see in others, as they know others hate what they see in them: and all recognize in one another what they detest in themselves, selfishness and impotence, agony, terror, and despair."
So, I guess a good way to put it is that, no matter what, there are redeeming qualities to be found in this world. No matter how much you separate yourself from God, there are people to be found that will be good to you and people that you will be good to. Hell is when you've finally and ultimately chosen to separate yourself from God and therefore are removed from all Love and Peace which is God.
And now that I've COMPLETELY gotten off-topic .....
