Theists' version of reality:

Evil exists for a purpose and there is a God that will rectify that evil. People will either go to Heaven or Hell depending on whether or not they submit to God and conform to the objectives that He designed them for.

Atheists' version of reality:

Evil isn't an actual thing, but something human beings label by virtue of a meaningless and purposeless collection of matter that just happens to give them that reaction. Morals are ultimately human constructs without any real content; and what constitutes "meaning and purpose" are arbitrarily decided as well -- making someone's understanding of these terms no less valid or invalid than anyone else's. People will simply die and become non-existent. There will never be any sort of ultimate justice for those who have been killed or harmed unjustly. The whole idea of 'justice' is also a fabrication, so it doesn't really matter anyways. And man wasn't really designed for anything; human beings just do whatever makes them happy and gives them the illusion of a "better life" (yet another arbitrary construct with no actual weight behind it).

In summary, objections to the theistic understanding of reality are just a frivolous and vacuous display of virtue signaling coming from a biological machine temporarily seeking a means to raise their dopamine levels.
