Yes, I think I have that "case" has one that happened in USA in the back of my mind...

But for instance, I totally understand the "wish" for revenge / justice of a cruel homicide victim's family...

It is not has simple has I pointed. Luckily I've never been so hardly attacked that I wish for that penalty for the offender.

I remember that back in my adolescence times, I had to go to the police for present charge against a couple of "kids" that assaulted and bullied in a pretty hard way my younger brother.

I remember returning home, and see my father and brother being punched and kicked in the ground by those "kids" and some friends that the "hired"... Very black memory and days.

Back then, I wish them that they should get what they deserve, and felt that I could extinguish them all...

Many years later, I understand that "eye for a eye" law it is not the "solution".
