Our instructors regularly commanded us to push our sparring to the point that immediate healing was needed for the worse fighter to survive afterwards, and I got a lucky blow to the head in at the same time an instructor was a bit slow with healing. The other kill was at the orders of the Sisterhood of Eiseth. My orders were described to me at the time as executing a minor criminal, but in hindsight I think it likely the only clear crime of the person I killed was vagrancy, and the intent was to ensure my discipline, ruthlessness, and resolve as opposed to a lawful purpose of society. I regret causing both deaths now, and understand doing so was evil, and also even of questionable lawfulness."
