So the world is ending, what to do?

In any case, make children!
Ethics do not matter, and children can provide some distraction. You can pretend that the children are important, fun stuff!

The children will be tortured, but who cares? Just shit them into existance, and then fuck off.

The second priority is ethics, ignoring them!

Pretend you are alone on this world - this part is important!

If you sense other people, that might lead to the ultimate sin, empathy. Don't do that, that makes everything so complicated.

Anyways, just shit on the floor. Like you do, right?
