Please Don't Fight the Hypothetical. I agree with you if you are only 99% sure, but the premise is that you know Omega is right with certainty. Obviously that is implausible, but so is the entire situation with an omniscient being asking people to commit suicide, or oracles that can predict if you will die.
But if you like you can have a lesser cost, like Omega asking you to pay $10,000. Or some amount of money significant enough to seriously consider just giving away.
I did say what I would do, given the premise that I know Omega is right with certainty. Perhaps I was insufficiently clear about this?
I am not trying to fight the hypothetical, I am trying to explain why one's intuition cannot resist fighting it. This makes the answer I give seem unintuitive.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
