The most obvious choice here is Baron Danglers. He is the man who was responsible for the arrest of Dantes. Having been jealous of Dantes success and likability, Danglers writes a note that accuses Dantes of being a Bonapartist conspirator and causes Dantes be imprisoned. Danglers is also jealous of all aristocrats, wanting so much to be a part of that higher class. He lies and steals to become a banker and marries an aristrocratic woman he does not love.
