Sleeping shapes, you rouse them from their beds; send the jets of light for them. You keep your face impassive behind the skull-like mask.
Apparating home when it is done, back to another day of teaching when you are done killing. You have no choice you tell yourself, you do what you can; you fight this war on both sides. But you know where you will go if you are forced to choose.
If it is between them… you hope it does not come to that, but, if you are totally honest with yourself, you prefer killing to teaching anyways.
