read this,mainly the last segment
74. Execution
If people were not afraid of death,
Then what would be the use of an executioner?

If people were only afraid of death,
And you executed everyone who did not obey,
No one would dare to disobey you.
Then what would be the use of an executioner?

People fear death because death is an instrument of fate.
When people are killed by execution rather than by fate,
This is like carving wood in the place of a carpenter.
Those who carve wood in place of a carpenter
Often injure their hands. -tao de ching
