The fight and subsequent killing between life forms of the same level is known as robbing another's life. It is murder. The oppression of the strong towards the weak is something the strong bring with a presence that can change weather with just a flip of their hands. Their killing of the weak is known as granting others death.
As for… those that had surpassed the categories of life, their killing would be the will of heaven gathering its attention on ants. That could no longer be known as murder, not could it be known as granting someone death. This was purely wiping off someone's existence from the face of the world.
It was like how an artist drew on a drawing board. Within the picture were lives, and when the artist swiped their hand across the drawing board, the picture would be wiped off, and along with it, all the lives within it.
