Man from origin has always been on a  quest for dominance over another man which results  into conflict  with another man which I will call  such scenario as (political tussle) bcs it is a quest for material and territorial possession, in cause of the crisis the Victor takes over the territory at the same time the spoils of war.

      Literally political philosophy has earlier  stated that man is a "political animal" in a lame man term this clearly means that man politically is on the quest to dominate his opponent at whatever cost be it brutal or with coercive force in other to claim the seat of power  which gives him legal right of ownership to resources within his domain.

     So my assertion is this, killing for political power can only stop being ethical with our political gladiators when they come to the realization that no man's life is worth a political office that is temporal while creating a lifetime enmity with opponents and citizens.
