Answer:
Yes, hail can kill you, but it's very rare. If there is a hail storm, the length of the storm, size of hail, wind speed, and amount of shelter will effect deaths caused by hail. Hail incidents are very unlikely in the US due to wether patterns and more shelter, but are more common elsewhere. Besides human deaths, hail will kill many animals, especially livestock without shelter, and devastate farmer's crops.
