To me, the question here is "To what shall the Will that resides within me be subservient?"
Someone once told me that the key to understanding the big stuff comes from starting with the small stuff.
So, let's say, in relationship to bacteria... It's alive. It is a life that participates in the Divine manifestation of Reality. It attacks me? Should I bow to the Divine Life within the unthinking, unfeeling bacteria and let it overcome me? No, give me poisons for it! Give me instruments for its destruction! Kill and spare not! Let's get this bathroom clean!
As one moves up the spectrum of life to more intelligent and feeling creatures, for instance, those that I kill for food, the question comes again? Who lives? Shall the Will that resides in me place itself second to the Divine Cow and die so that the less-thinking, less-feeling creature may live? Some choose that path and the experiences it offers. Personally, I kill and eat, and I survive at the expense of the animal's life.
Moving up to human/human considerations, I think one must exercise much greater care in application. But the question comes again: "To what shall the Will that resides within me be subservient?" The fellow human can be considered just as fully an expression of the Divine Life and Will as I am. In my opinion, the message of Hadit is based in survival-mentality: "This is what to do to survive." Now here, we reach a level where the survival-mentality has some choices to make as to quality and length of survival. You may attempt to kill and stamp down everyone who seems to stand in your way, but the survival-mentality of the collective will descend quickly to protect society by instead killing you. It would lead to a very ugly and very brief life that would only make sense in a very socially primitive setting where survival and dominance rule alone. As a result, in the context of survival within society, the injunctions of Hadit make more sense if they are applied more symbolically.
I guess at the end of the day, I see Hadit's message as sort of.... the father's blessing on the survival of the son: "If it all goes down bad, and you're in a foxhole wondering about the correctness of shooting other humans who are intent on killing you... Then, my son, feel the sharp, venomous blessing of the will to survive! Kill and spare not! You have my blessing to survive!"
One may, if one prefers, submit one's own life to the experience of death at another's hands. Though that would not be the perspective and advice of Hadit, it could be said to reflect the perspective and advice of his counterpart in Nuit, who is associated with the death of self-orientation for the sake of all-orientation.
Compassion is the vice of kings. It ultimately leads to the king's death. But, one must ask, what kind of death was one born to embrace?
Choose your vices appropriately.
