Iago's main core lies in self-control and motivation -- he believes himself to be a man of simple free will, and unlimited freedom. Unrestrained and in control of the chessboard -- he assumes both the external world and (mistakenly) his internal world are under his control, but they may not be.

Personal freedom is quite a misconstrued concept. People miss the fact that vaccinations are not as personal as they seem to be. Vaccinations have a significant effect on the population through herd immunity.

Can someone clarify in general, what the hell is personal freedom?
