In the biggest part of this country, it isn't legal to kill
someone over property. Morally, it's reprehensible. What
value of property do you think is worth someone's life? Would
you kill someone for stealing your garden gnome? Or do they
have to take your toaster before you'd shoot?

aren't stupid. They know the risks. If they decide to break into an
occupied house, they've decided that they'll harm the occupants.
The homeowner responded appropriately to the threat.
