This is a brief article that analyses the moral issue of celebrating bin Laden's death. Basically, there are four possible reasons to celebrate:
(1) to celebrate for his dying
(2) to celebrate for the defeat of an enemy in war
(3) to celebrate retribution for heinous criminal acts
(4) to celebrate his being disabled and rendered harmless
I agree with the official Catholic position, as stated in the article. I appreciate that bin Laden is rendered harmless, but I take no part in celebrating death, revenge, or war. To do so, is to emulate bin Laden's way of thinking. I choose to emulate Jesus's way of thinking.
