Going to Hell -- Not So Bad?

Basically, I'm an atheist, but religion and God are pretty much so ingrained into everyday life, that one can't help thinking about stuff.

And one thing I was thinking about is the concept of going to Hell for being bad (lying, stealing, fornication, murder, child molestation). And I got to wondering -- Why would Satan punish people for doing his work (being evil)? Isn't that like God punishing priests and rabbis for doing his work (doing good)?

So it seems to me that it must be God who is in control of Hell, and not Satan. Which must mean that either there is no Satan, or God and Satan are one in the same.

Or there is no God and no Satan at all.
