For me, there is nothing that would be off the table. Everything would be a possibility open for consideration. I would not set anything aside from consideration in advance. There are many things I would certainly not want to consider, and many things I don't think I would do (as I mentioned above, I wouldn't kill someone to take their stuff, but I would kill them to defend myself).

If the time comes, would I actually kill someone if they were intentionally threatening my survival? That, I can't answer. I can only answer that, yes, I have trained and equipped myself to do so. But would I? I can't answer that in advance. FWIW, I don't consider self defense to be murder. Some people do. I don't.
