Corns also eat snake sausages too (made by T-rex).
Not only does live food have the potential to kill your snake, it can also spread parasites and bacteria to your snake which also have the potential to kill it.
Also, frozen and thawed mice are easier to digest because the tissue of the mouse breaks down after being frozen and thawed (was in the cornsnake manual somewhere, but you can check there to verify if you don't believe me).
