Would you worship god to avoid going to hell?
The response below assumes that a person is otherwise living a normal moral life, doing good, etc. This is specifically talking about the belief/worship requirement. Some Christians believe that anyone who is a good person gets into heaven - we're not talking about that position here.
The answer varies from atheist to atheist, but the question could be phrased in a different way.
If a dictator of your country ordered you to praise him every day, or be executed, would you do it?
Some would, some wouldn't, and some would pretend to do so while forming a resistance group. The question does not paint a flattering picture of God, if he set up the game such that a person would be tortured for eternity for a thought crime - a crime that was little more than failing to stroke his ego.
Some would say that God isn't sending us to hell as an evil dictator, but rather we automatically go there, unless he saves us, if we merely "believe in him". An analogy often given is that you're drowning in the ocean, and God is throwing you a life preserver, and you're choosing not to take it... so you're really choosing to go to Hell.
What atheists see from this particular mythology, is either a God who decided anyone who's not perfect automatically goes to Hell, or a god who is not powerful enough to override such an injustice (though that's a separate discussion).
In either case, this is not a being deserving of worship. I'd like to think I'd be strong enough to resist.
Even if God is trying to save us, belief/worship being the requirement for salvation is despicable. He's God. The salvation requirement could be based on peanut butter consumption if he wanted. For some reason, according to this book (depending on which sections of the book are read, and who you ask), believing without evidence is what's inexplicably needed.
