I owe it to everybody to keep them alive, to keep them safe, to keep them from ever going through what I went through. Nine times out of ten that'll mean putting myself in front of the gun for 'em. But sooner or later someone comes along that can only be stopped by going to the grave. How many people are you gonna let someone kill, maim, torture, rape, just 'cause they've got a family and loved ones? How many victims does it take before you decide maybe, just maybe, it ain't worth it to keep somebody alive just so you can sleep better at night?

Better question, why do you sleep better at night knowing someone's out there killing people and destroying lives than you do knowing you did a terrible but necessary thing?
