But there's also the case where X is a copy of you, where cooperating does help, so it seems to be a better choice overall.

There is also a case where X is an anticopy (performs opposite action), which argues for defecting in the same manner.

Edit: This reply is wrong.

No it doesn't. If X is an anticopy, the situation can't be real and your action doesn't matter.

Why can't it be real?

Because Omega has told you that X's action is the same as yours.
