What are some examples of Machiavellian heroes?

When defining a Machiavellian Hero, one must remember that
the word hero in this context means protagonist (main character);
otherwise, the combination of Machiavellian and hero becomes an oxymoron. That being
said, the term applies to a protagonist who seeks political or social gain at any cost.
Below are several examples.

Shakespeare's
Richard III--briefly put, he orders the murders of family members in
order to obtain the crown.

Milton's
Satan in Paradise Lost--as Milton portrays him, the
beautiful angel Satan is willing to risk all, over and over again, in order to grasp
ultimate power and revenge.

Khaled Hosseini's
Amir in The Kite Runner--this is a more modern
version of a Machiavellian hero, but in the first section of the novel, Amir cowardly
betrays his friend and then frames him so that his father can focus solely on him. Amir
does change as the novel progresses and loses his selfish tendencies, but his
willingness to sacrifice anything or anyone to obtain his father's approval is shocking
and results in long-term repercussions for him and
others.

Napoleon from
Orwell's Animal Farm or the "real" Josef
Stalin--both use others (such as Snowball or Trotsky) until their use is
expended and then annihilate them.
