I have just discovered a wonderful ethical dilemma.
A man is hiding in your closet, and another man is standing before you in the doorway. You know that each wants to kill the other, and you suspect both are evil, but you don’t know for sure. Man number one, standing in the doorway demands to know if the other guy is in the closet. If you reply in the affirmative, he will shoot the man hiding in the closet. If you deny that man number two is hiding in the closet, he will pop out and shoot the blighter standing in the doorway.
Now, both men could be equally evil, one could be slightly eviler than the other, or one could be the evil train robber and the other a hero mounted atop a white horse. (Aside from the complete absence of handy monochromatic hats and/or quadruped transportation, that is) You just don’t know.
Assuming that it’s a binary situation, what is the best ethical choice?
In retrospect, I’m probably I’m the last person on the planet to come up with this situation, but it still amuses me.
