Serious business. You really shouldn't cut the sentence in half to remove context and create false impressions and expectations. Right after "and suffer death" the sentence continues to say:

, or imprisoned and fined, and incapable of holding any U.S. office.”

There is a process of law, and it should be observed. May they receive their just desserts, serving themselves as they deserve, up to and including death, but from justice not vengeance.
