“The world is real; the suffering of others is real; one's actions can sometimes irrevocably determine the destiny of others; the mistakes one makes are often transmuted directly into others' pain; there is sometimes no way to undo that pain-the dead remain dead, the maimed are forever maimed, and there is no way to deny one's responsibility or culpability, for those mistakes are written, forever and as if in fire, in others' flesh.”
