Why Solid Snake Kills Big Boss

He told snake to infiltrate the base that venom was leading.
Why solid snake kills big boss. Stop trying to pass head cannon as fact. At the end of mgs4 the patriots are destroyed and big boss is freed his body is repaired using body parts from liquid and solidus and that s why you see him and solid snake in the same scene at the end of mgs4. Solid snake thought he killed big boss in metal gear 2 but big boss lived although he was very close to death. Kaz miller must have lied to solid in mg1 big boss screwed venom miller isn t in that game.
His body was essentially kept on ice by zero so he could suffer. In metal gear 1 which is the next game in the time line big boss is the leader of fox hound and he sends solid snake to inflitrate outer heaven and stop them. After that big boss betrays foxhound and solid snake learns that big boss is the true leader of outer heaven. There s no good or bad guys in the metal gear saga only shades of grey at a certain point both bosses lost sight of what they really wanted and ended up tearing the world apart as a result with big boss even lamenting it in later games.
Anyway one thing led to another solid snake found out a few things and discovered that foxhound commander big boss. Big boss is kinda a dick but not that evil.
