Maybe I'm being petty, but I'll tell you what sucks most about all these jerks using "God's Plan" to justify all their evil bullshit:

When we die and there's no afterlife, we won't be able to rub their noses in it.

We'll be dead. Which means, if you want them to get what they deserve, you kind of have to be rooting for hell. And of course, this means if hell exists, you're likely going to wind up there too for thinking all these nasty thoughts. Which I suppose means that you might get to torment those liars and hypocrites while in hell, but the whole deal still sucks because that means hell will basically just be what we already have right now on Earth. Accept, at least the bad guys will be suffering. I suppose there's that.
