Point in case: if you unrightfully copy a copyright, then the duplicated copyright has no grounds to enforce itself, as its creation was unlawful.

THEREFORE: You can delete the duplicated pages if you want. The other wiki can do nothing about it, as you are simply repairing the damages that were created.
