Christianity

All of what you've said boils down to "God decides because he is God." You don't see any issue with that?

It doesn't sound the least bit disturbing to you that an all powerful being would actively choose to make people suffer when they are fully capable of not requiring it? The equivalent of a parent who beats the shit out of their child from ages 4 to 5 and then switches to showering them with affection doesn't sound like anything I'd like to engage with.

The whole "God created you, so that gives him the right to demand your worship" thing is also just plain creepy. If your parent beat and raped you, would you consider them worthy of your love?

Ultimately, I don't think you have asked this question in good faith. You don't seem interested at all in fully engaging with the responses people give, and seem more interested in picking specific bits out to latch onto that have (supposedly) easy answers.

So I'll leave you with an easy answer: you can believe in god and think we are all doomed or whatever, just don't make the lives of everyone else around you worse by being a dickhead. That's all Atheists ask of anyone, and I think its a reasonable proposition. As for the whole "this is temporary but heaven is eternal" angle, well, there are ways for people to take shortcuts there and they don't tend to do that, so clearly something down here is worth experiencing - maybe try to look for those things before wallowing in fear.
