Ok, Peetza,
First, when I'm wrong, I'm wrong,
No he's not. He might be guilty of ONE felony.
I was thinking that the BG has done this before, but, my bad.
Second, don't take this as a personal attack, but you are too smart to be committing so many logical errors.
Here you go:
Error #1 then start your own thread. We are discussing the scenario in the OP
The OP doesn't give a "scenario." He is asking a broad, open-ended question looking for a debate and distillation. His "scenario" is unanswerable. Are there others in danger? Does the BG have a weapon? What kind of weapon? What kind of crime, if any, is being committed? There are too many variables to honestly answer the question.
Error #2 Not all burglars are dangerous
No, most burglars aren't dangerous. Someone breaking into my home isn't a burglar, if I'm home, under Florida law, he's a home invader, and that's a felony. The burglary and home invasion statutes overlap, but home invasion is definitively an upgrade.
Title XLVI CRIMES
Chapter 812 THEFT, ROBBERY, AND RELATED CRIMES
812.135 Home-invasion robbery.--
(1) "Home-invasion robbery" means any robbery that occurs when the offender enters a dwelling with the intent to commit a robbery, and does commit a robbery of the occupants therein.
Error #3 Since you don't have ESP there is no safe assumption. Assumption = Guess
You are assuming that the BG is a burglar. He might be a Meth head thinking I'm the dealer that just cut his supply. He might be a Satan worshiper who wants my heart for an evil ceremony. He might be there to rape me or my dogs.
The point is, you accuse me of assuming, but make your own assumption. I have evidence on my side. He could break in for the several hours I'm at work. By breaking in while I'm home, it is perfectly logical for me to "assume" that he intends to do harm.
Error #4 Should a misdemeanor be a capital offense
That's a straw man argument. No, it shouldn't, nor should home invasion. I'm not an executioner, I'm not the state, only the state can make things offences. I'm not determining what constitutes an offence. I'm simply sleeping in my bed, or watching tv, minding my own business, and if needed, protecting myself.
I'm not advocating killing people for any reason. The OP asks is there a moral duty to retreat. That is a philosophical argument. Most of the people are conflating practical and philosophical. If I am where I'm supposed to be, and I have taken reasonable precautions for my safety, then no, there is no moral duty to retreat.
That doesn't mean I won't retreat, I'm just saying that there isn't a moral duty.
If someone engages in action that puts him or her in the position of primary moral agent or actor, then that person is responsible for what happens.
The morality comes into play depending upon who precipitates the action. If someone breaks into my house, it isn't my responsibility to spend time determining their intent. By his ACTION, he has placed himself in a position of danger. If I am required to determine his intent, I am in danger if his intent is to harm me.
No moral code I can think of would require ME to endanger MY SAFETY because of his ACTION.
You are asking the equivilent of me determining if the guy driving in my lane is drunk or not. I don't know if he is going to swerve back into his lane or not. If I he hits me, well, at least I'm not morally responsible. I don't care why he's in my lane. Similarly, I don't care why an "uninvited" BG is in my home; I must assume the worst, at least in today's world. To do otherwise, while it may be honorable, is stupid.
