Burglars shouldn't be killed as a matter of course. but I'm not going to discuss if they intend to do me harm If I encounter one in my house they can run away or if It comes to a fight I'm going to stop them which means inflicting enough hurt to stop them any way I can.
if they die well tough burglar runs fine if they don't. I don't have any problem at all with them being killed.
once I stopped them I'd, of course, phone and ambulance render first aid might be too late by then though
.
Dont have any weapons close at hand and the dog would probably chase them off.
