“when you are faced with a man who wants to kill you, you are going to have to probably kill him in order to survive.
I hope that, in this moment, you will not care for philosophy, humanity or ethics, and that you just going do what you have to do, and survive.” Selco
These two paragraphs sum it up for me. Recognize that you have arrived at the moment where there can be no more deliberation. I hope it never comes to that time.
