Another thing,

A human hand is still needed to kill a person. Yes, we call it a 'state killing' but its a physical being that has to turn that switch, press that button, pull that trigger or put a noose around that persons neck. A human has to live with his actions of killing someone.

And what about the doctor who needs to assess if the prisoner is fit enough for execution and declare the prisoner dead after the deed is done. A doctor who has taken an oath to never deliberately hurt or kill someone.
