The bodies of the three ghost messengers lay on the ground. Their deaths were extremely tragic. What was even more tragic compared to their deaths was that while their bodies were being strangled, their souls were being crushed at the same time.
This was a true form of extermination. It does not give you any chance at all.
Just like on a football field, if you were ruthless enough to cripple someone with a black foot, you would be condemned by the public. This is because everyone depended on their feet for a living. The act of destroying someone's livelihood was too ruthless.
Similarly, destroying a ghosts' body while also destroying their soul was truly a death sentence.
