What Would Jesus Do? That's not really a question, is it? We know what he would do. In addition to turning a whole lot of water into a whole lot of wine for some couple's wedding, he would lay down his life for our sake, and in so doing, conquer death. Then he would rise from the dead and have a barbecue on the beach.
There are other people who provide grist for the metaphysical mill as a thought experiment, whether we would really ever do what they would do, or not.
What would John Moses Browning do? (My favorite)
What would Marcus Aurelius do?
What would Winston Churchill do?
What would Ronald Reagan do?
On the other hand,
What would Josef Stalin do?
What would Pol Pot do?
What would Idi Amin do?
What would Hamlet do? (Even he did not know)
Well then what would the Dread Pirate Roberts do?
What would Master Chief John 117 do?
What would Gordon Freeman do?
What would Colonel Jeff Cooper do?
What would Clint Smith do?
What would Larry Correia do?
You get the picture. It expands one's horizons.
