Ok. Let's start with the basics since you guys are having difficult grasping the point. I know AV loves these itemized question lists, but I'd like anya to answer them also. Answer each of the following:
Where did hell come from?
Who was hell prepared for?
Who goes to hell now?
Forever?
Does God want those going to hell to go to hell?
Why are those whom hell was not prepared for going there when God doesn't want them to go there?
What crime or sin is justifiably punishable by an eternity of suffering?
Can't an omnipotent God get what it wants?
I am not one of those people that you called for an answer to these, but I am bored so I will attempt to answer them anyway.
Where did hell come from? Well, hell actually isn't described very well generally speaking. Its creation is never mentioned, and most of what "we" (Christians included) "know" about it comes from speculation. Some have suggested that it was a failed attempt at creating heaven (an omnipotent god shouldn't be capable of failing), others have stated that it was created after the whole lucifer fiasco to hold all of the fallen angels (in short, angel prison) or that it was created after the fall of mankind. However, there is no official, provably correct answer to this question, and the answer will vary depending on who you ask.
Who was hell prepared for? Well, this ties in to when it was created, but I would say it was originally for the fallen angels, and was later used for "fallen" humans. I humor myself sometimes imagining it as god's trash bin.
Who goes to hell now? Extremely subjective. This will vary depending on what religion you are of and what sub sect you are as well. Big dividing points are whether or not nonbelievers go there, as well as whether just being a believer and not necessarily a decent person is enough. But, since only certain crimes specifically are mentioned in the bible, it truly is impossible to draw the line where sinner ends and saint begins.
Forever? Again, depends. Most people will say it is, but an increasing number of people suggest that after a certain point, the sinner's soul "dies" and they completely cease to exist (as if that is any better).
Does God want...? Most people say no. But, given that god supposedly gave us free will, and thus the capability to choose to do evil deeds as opposed to making us be good (fair enough, people do not rise to the occasion if there isn't an occasion.). Then there are the religions that feel that people do not have free will, and those who will be saved has been predetermined. They usually justify this by stating that some people must fall for others to be saved (-_-).
Why... to go there? Mostly explained in the prior question.
What crime or sin...? Child murder. Completely my opinion, but just saying, I don't shed tears for people such as Hitler or Pol Pot. If there is a hell, they are there, and I am perfectly ok with them suffering indefinitely. Also, most people suggest (and this is graphically detailed in Dante's Inferno) that the punishments people receive are relative to their crimes (atheist but otherwise good: eternity of listening to bad country music, I don't know). I suppose an infinite existence is still better than complete nonexistence.
Can't and omnipotent God get what it wants? Absolutely. You assume, however, that god feels that the best course of action was making everyone perfect.
Ultimately, god wanted people to prove that they were worthy of paradise: without any temptation or sin, how can someone prove to be good, when just everyone is made that way? Plus, it would be really, really boring.
You also have to consider that, as far as we can tell, very few humans were directly created by god. We are the descendants of initial creations, and nothing suggests even then that people were completely perfect.
But yes, if god wanted a world of puppets, god could have played the puppeteer.
