What difference is if he resigns and Pence pardons him? Ford pardoned Nixon.
Basically, I'm against executing and even imprisoning past Presidents. Especially today where you have very corrupt liberals.
In any case, it's not unlimited power, though. A presidential pardon has no effect for civil, state, or local offenses. Federal pardons don't apply in cases of impeachment either.
