I consider Solid Snake the major villain of the Metal Gear Saga. Why? I'm going to explain you WHY.
Here we go: the Patriots were an organization that wanted to accomplish the last wishes of The Boss. Zero, which was in the unit S.A.S. with The Boss, along with Big Boss, Para-Medic, Sigint and then EVA and Ocelot, the Patriots formed.
Liquid and Solidus began to challenge the Patriots (the incident on Shadow Moses in 2005, the Crash of Big Shell / Arsenal Gear in 2009, and 2014 with the uprising of Liquid Ocelot), but each attempt, the Patriots sent Solid Snake who seized his two brothers.
Although Solid Snake (as he himself says in MGS2), manages to elude the control of the Patriots, remains a pawn in their hands. The missions of Shadow Moses and the Uprising of Liquid Ocelot are assigned to him by Roy Campbell, a friend and companion of Big Boss from the time of St. Hyeronimo.
However, Solid Snake is not safe from the Patriots, as Roy Campbell is connected in one way or another to them.
So Solid Snake is always a pawn of the Patriots, forced to stop his family to break the hegemony of the Patriots.
From Liquid to Big Boss, Solidus included, have always wanted a free nation and a haven for mercenary soldiers from around the world. Big Boss called Outer Heaven. Outer Heaven is not never survived so long because every time Solid Snake would stop them, by the hegemony of the Patriots thrive.
That's why Solid Snake is the villain of the series from my point of view: every time someone (his family in almost all cases) wanted to stop the Patriots, Solid Snake will eliminava.ogni time someone (his family in almost all cases) wanted to stop the Patriots, Solid Snake them what eliminava.ogni once someone (his family in almost all cases) wanted to stop the Patriots, Solid Snake them eliminated. This is a hero? A hero who fights for freedom? Do not make me laugh. Liquid, Solidus, but especially Big Boss were heroes. Not Solid Snake. He may have destroyed hundreds of Metal Gear, but that does not make him a hero.
Big Boss knew that Zero did not fulfill the last wishes of The Boss, and decided to found Outer Heaven.Big Boss knew that Zero did not fulfill the last wishes of The Boss, and decided to establish Outer Heaven.
In this saga, the good and bad appear and change from the point of view.
