The answer is "Yes, but it's understandable". I didn't personally shout for joy or revel in his demise. Indeed, I had moments of regret. I am strongly against the death penalty and I'd have preferred to see him brought before a US court. That said, this method for removing him as a threat was efficient, safe, and not the most villainous act we could have committed.

So, my ideals (Taking a life is just universally bad) are in a staring contest with my pragmatism (We have to defend ourselves) and, as is the norm, my pragmatism is winning. But my ideals still won't let me rejoice in it. Somber and considered reflection are the right response for me.
