Yes.Did you come up with that??
Another one:
Think of someone who is your friend (not your best friend, but someone who is important to you). That person is going to be attacked by a grizzly bear. This person will survive the attack, but the extent of their injuries is unknown. They may only need a few stitches, or they may spend the rest of their life in a wheelchair eating only liquids.
Now, you have the ability to magically stop this attack from happening, but there is a price to pay. For the rest of your life, wherever you are, it will rain. Maybe heavy showers, maybe only a light drizzle, but it will rain. You will never see the sun again.
Would you stop the bear?
