Gregor, I don't even know if my view is right, let alone morally superior, and I certainly don't think I'm morally superior. I was merely being honest when I said I didn't think I was capable of using lethal force (and the conversation had to do with being attacked, not being murdered). But I've never been in such a situation, so I can't say anything with absolute authority.
You also misquoted me, or perhaps I misunderstood you. You said the key to human success was the pursuit of self interest - if you think that is interchangeable with the human instinct to survive, then I did not understand this.
And I am glad that there are people who set aside self interest, to see to the needs of others, and not for personal gain. Such people do exist.
