yeah there are lots of great theories think about the following:

Tupac's alias is Makaveli. Though the spelling is different, Nicollos Machiavelli was a 16th century Italian philosopher who wrote on how to gain and maniupulate power and advocated the staging of one's death in order to evade one's enemies and gain power. A person who is said to be hign in Machiavellianism may undertake practices that are conflicting with eithical standards in order to gain the result desired.

In Machiavelli's book Discourses Upon the First Ten Books of Titus Livy, in Book 2 Chapter XIII he says "a prince who wishes to achieve great things must learn to deceive". This is Machiavelli's main idea and is the connection between Tupac and the writings of Machiavelli.
