I must be lucky - I don't know any narcissists, not that I can readily identify anyway. I can't think of a single family member or friend that I would not want to have with me in a survival situation. I have one or two that might need a little extra training because they're a bit on the "less knowledgeable" side regarding some things, but they're not that way because of narcissism or other negative personality traits. I don't mind training someone how to sharpen a knife if they've never done it before. Or how to safely handle a firearm. Some may have never started a fire without the help of charcoal lighter fluid or a tank of propane. But those experience deficiencies could be easily remedied, and they would be valuable members of the team.
