The laws of the land provide for the punishment of wrongdoers, and the duration of that punishment is according to the enormity of the crime.

If a man steals his neighbor's chickens, the duration of his punishment would probably be a few days in prison.

If he burns his neighbor's house, the duration of his punishment would probably be a term of years in prison.

If he takes his neighbor's life, the duration of his punishment is death.

There is no limitation to that punishment.
