@anonymousangel okie. Imagine:
I rape your mother one time. You find out and you let me free.
Since I committed a sin before there is a high chance I will do again
...
So I rape your mother 2nd time. Will you still not give me death penalty? Or you will wait for me to rape your mother 3rd time?
Any logical person who respects their sister mother would like to kill that bastard.
