Because a person who vanishes does not suffer for long, and more than that, they do not face anything.

They are simply gone, and the fear of it is spent in an instant, and the world moves on, and the only lasting effect is on the soul of the one who did the vanishing, who becomes, a little more with each darkness, the same kind of monster as the people they were punishing.

That is the trap the old life sets and calls power.

The light is heavier.
