I would like to talk about the christian concept of hell. First, it should be noted that there is no single christian idea of hell. If you ask ten christians you likely get twelve different answers.
The concept of hell is important because it is the second most preferred method to turn people into christians. (The most preferred method is, of course, to raise their children into christianity, not allowing them awareness of the outside until they are completely shackled to it.) Now, the concepts can generally be divided into two groups, a simple separation from the christian god or a setting in which the god or some demons or whatever are engaging in torture. The considerations for each of the possibilities are different. I shall address them separately.
If hell is simply a separation from the christian god, I can find no fault with it. But in such a case, I have no cause for alarm. Did you know that I have been separated from the president of the United States and from queen Elizabeth of England for my entire life. It hardly bothers me any more.
On the other hand, if there are active tortures, regardless of who is doing the direct torturing, any god (or any other being, for that matter) who would send people there for all time is wicked. Does he delight in suffering? It matters little when people say it was only meant for Satan and his angels. The question is still the same. Does this god delight in suffering? If he does, he is a wicked monster and not worthy of worship.
