It is human nature to seek culpability in a time of tragedy. It is a sign of strength to cry out against fate, rather than to bow one's head and succumb. Inevitably many will fault the hands upon the sword which felled the Institute, the Brotherhood of Steel. But the Brotherhood merely performs the duty of its office. To further fear them is redundant; to hate them, heretical. Those more sensible will place responsibility with those who forced the hands of the Brotherhood. With some fortune, they may foster this hatred into purpose, and further rule their own fate by coming to the Commonwealth's service.
Yet ultimately, it was I who set these events into motion, with a single shot from my plasma rifle.
