If you are the type of person who thinks there is knowledge you could share to help someone and you don't thrn you aren't a person I want to talk to anymore. Whether or not they do anything with the information is up to them, but if you don't Share it out of some petty spite or smug superiority and that person dies or loses a leg you are a piece of trash and it will haunt you forever. Be a good and right person for it's own sake. The recipient is irrelevant.
