No one wants to be where God isn't and Hell is that place. Everything you see now as God's proof of existence, the flow of air, the rain, the sunlight, the beauty of nature and it's breeze, the love of people and the peace that Christianity is preaching are the things that many in Hell wish to have. And once you go there and you don't find these things, you will be hit with a constant regret. God created that place for Satan and his demons not for his people.
