Its kind of an "overzealous" punishment... and sick... I know that rape is terrible but being crucified is like having body parts cut off with a dull machete... it should be more like. Attempted murder would be jail time but there are levels of attempted murder like shooting someone vs. hitting them with fists. Quatering for murder is a little too much but I guess its fair...

And loss of a hand for theft... the ways of the Middle East... I would arrange the punishment differently
Rape - Loss of sexual organs.
Murder - For every death, cut off 2 body parts.
Larceny - Guilty person is imprisoned and the victim gets the guilty persons assets.
Armed Robbery - Loss of hand(s)
Attempted Murder -
Shooting - Loss of arm(s)
Stabbing - Loss of arm(s)
Hitting/Beating - Loss of hands
Other - Depends on extent of crime.
