Depends on the nature of the hypocrisy. You wouldn't give the death penalty to a little girl spreading rumors in her school, even though she's a hypocrite. She's spreading corruption, but it's not major, legitimate corruption. However, you might give the death penalty to a federal double-agent or a national spy in a war. This is definitely major corruption. It depends on the magnitude of the crime.
Of course, it's guilty until proven innocent. You can't declare someone a hypocrite unless you're absolutely sure.
