Thanks for your feedback, I appreciate it. “An eye for an eye” is a medieval practice that doesn’t fit in modern western society. You don’t have to cut someone’s hand to deter him/her from stealing. If someone is a menace to society, logically he/she should be locked away.
The confinement duration, of course, should be determined by a judge but I would vote for a maximum penalty of life in prison if a global referendum is conducted on this matter.
