Let's say someone is, for whatever reason, determined on some course of action and that you do not want to be involved in it or affected by it and moreover you also genuinely believe that it is so wrong that it will adversely affect even the proponent - what would you do ? Would you resist at least to the extent you will be affected or would you provide active support and cheer the other person on ? Whatever your answer, I think people would at least inwardly admit that they would do nothing to bring about the success of the other person's intentions.
