NOBODY has argued that a burglar didn't deserve "some sort of punishment". People are talking about whether committing burglary means you deserve to die.
I haven't read that into this thread.
I think people are arguing about whether a burglar still retains any rights after he has chosen to step outside of recognised societal norms by entering another’s private dwelling with the intent to deprive that person of their lawful property.
If we agree that the burglar HAS abdicated rights by his CHOICE of actions, then the questions become interesting as to which rights he forfeits.
Personally, I believe he doesn't automatically lose his right to life.
However, I believe he should lose his right to protection under the law of the land.
You can bring up any number of reducto-ad-absurdum examples to argue against this stance.
e.g. If I'm speeding, doing 40 in a 30 limit, does that give someone the right to bring me down with a sniper rifle?
However, in my mind, the principle stands, that if I choose to step outside of the law, then the protection I receive from the law is commensurately reduced.
