This is where we differ. I don't care remotely about fairness to criminals.
I've been burgled twice and wouldn't have the slightest concern what happened to the scum who did it if it prevented them from doing it again.
If they don't like consequences perhaps they could, you know, not commit crimes.
Ok so a couple of questions for you then;
1) If you were to be involved in an accident, where you killed someone, and it was deemed you were at fault, would you suggest it reasonable to be executed for it?
2) What if you drove over the legal limit for alcohol?
3) What if you were speeding?
Considering the sentence for planning to, and killing someone, is about 20 years, execution for burglary would seem... Extreme?
