When the right moment arrives, you will act without hesitation to stop the beating heart of another human being. The next day, or the next minute, or even seconds later, you will do it again, and then again. You will do so without hesitation, remorse, or passion, as a pure and unquestioned expression of your mission and of your craft.
When you are finished you will return to the society you have just risked your life to protect, and live among those who will never say “Thank you” or “Well done!” nor, in fact, have any idea what you’ve done.
