Do you feel even the slightest bit of guilt if you're happy that a known terrorist is dead? I've been mulling over this a good portion of the day.

Yes, many innocent lives will hopefully live longer, now that (taking a quote from "Murder on the Orient Express") "the repulsive murderer has been repulsively and, perhaps, deservedly murdered". I just don't feel right in celebrating it. Of course, I wasn't fond of "Ding! Dong! The Witch Is Dead!" either.
