Any predator will be extremely wary of anything that can cause injury, since injury can interfere with the ability to eat, which can cause death.Scare it off IMO, it's not like it's matsuki.so hypothetically, if you are being followed by a bear, and you pick up a decent sized rock and hurl it right into the bear's nose, are you more likely to scare it off or piss it off?
If you are perceived as a threat, then you will probably be left alone - unless the predator is desperate or defensive.

In the wild, getting hurt is seriously -EV. The problem is convincing the bear that you can hurt it, particularly if the bear is especially hungry/desperate.
