The same could be said if you refuse to do the work and it's given to any other person who doesn't morally object (off-shore or otherwise).

Unfortunately, the ethical chain here is only as good as it's most unethical link. Then again, most people really don't have a good feeling being the corrosive link.

I don't know what you mean by "ethical chain", but whether something is the right thing to do is independent of whether other people are acting morally or not. Just because others are morally corrupt does not justify one's own moral corruption.
