I'm looking for common phrases similar to "What would you do?" I'd like any phrase that signifies the call to action to make a difficult hypothetical decision. For example, "Take your pick" is a possible answer because it is a common phrase, but it doesn't work that well in context of making a difficult decision so it wouldn't work.
I know this is a really specific request, but ideally the phrase really captures the essence of difficult hypothetical decision, perhaps an ethical dilemma.
E.g. "Would you prefer a slow and mildly painful death, or a quick and very painful one? WHAT WOULD YOU DO?" (replacing what would you do with something else)
