I think it's good, at a basic level, to refuse to do things that shock your morality, even just a little bit. I was once told our company was going to be pitching to do work for one of those companies that sneak charges onto your credit card and then claim that you asked for it. I said, "You'll be doing that project without me." It's a risk, that you might be considered to be not a team player, but I think it makes you feel better in the long run.
