Either let you, the player decide the mental state of the character through his questionable actions, or tell you exactly how to feel through cut scenes and dialogue.
You don't want to kill, but you do if you want to save your friends. The story is cliched and has been done a million times before, yet, what is different? Oh, that's right, you are a beta male. Long story short, you escape, your brother dies and you are taken in by the rebels on the island. You wake up in a cage with your older brother, being lectured by the main bad guy (for half the game), Vaas. I'll get into the conflicting genealogy of the island itself in a moment. You all are skydiving and get off course over Rook Island. The narrative is thus: you play Jason Brody, a collar popped white beta male on vacation with your brothers, a stoner and a couple girls.
