in American history is Benedict Arnold, who destroyed his own fame and previous brilliant career, accomplished nothing but his own exile, and affected events much more as a hero (before) than as a traitor (after).

The Most Underrated Criminal

is Ted Bundy, who is almost single-handedly responsible for several tons of miserable fourthrate fiction in both novels and film. He has a lot to answer for, that geek.
