Im not sure you grasp the concept of Atheism. There is no pretending, there is no "uncomfortable" afterlife. There is alive...and DEAD. Period. No cloud floating with angels, nor brimstone and hellfire. Just worm dirt. There is no heaven, no hell, no limbo, no God, no devil.
But you did bring up a valid point unknowingly. Religion is based in fear. Fear of the unknown, fear of reprisal, fear into "morality".
Actually, there is some thought given to what happens when we are dead. I'm an atheist and find it at times quite disconcerting to realize that when I'm dead, that's it. Nothing. The hope that Christians have doesn't belong to me and in a way I envy them that. As for fear, yup. Fear has a lot to do with religion but nothing to do with faith. I choose not to believe in a God, god or gods. I choose to not believe and refuse to belittle those that have a genuine faith in Jesus that they not only profess but live.
Believe me, there are plenty of fake Christians that are assholes, but there's more than enough atheists that are fucktards as well. The former are liars and the latter are just being, well, fucktards. I haven't a clue as to what tbombz really believes but can guarantee its not in the Christ because if you're a man and suck the dick, you lose the kingdom. And that is the word of Sam Kinison.
