The short answer is: no, I don't regret protecting the mission.

The long answer is: I have a peculiar definition of protecting life. Enrico and I weren't close. We were colleagues, but that was as far as it went. I was assigned to a position he was hoping to fill, which created a certain amount of friction. However, we kept personal differences out of the work place. I will admit, no friendship was lost when I eliminated the threat he presented, to the mission, to the work I was hoping to accomplish for a different employer. Sometimes one has to sacrifice a life to protect others.
