From what primary facts does such a moral imperative arise? I would suggest that there is no such moral imperative at all and no one should accept that there is until the foundation of such an imperative is clearly and rationally stated. Many make the presumptive leap that morality must necessarily be altruistic with little rational basis for that leap. I disagree that genuine altruism is a moral necessity and will do so until I see substantial, rational arguments as to why altruist moral systems are superior to egoist moral systems. (note that benevolence != altruistic and exists comfortably within egoist moral systems).
