Now, this is a real choice. It involves conflicting emotions of equal strength. One must not confuse decisions, opportunities and choice. Decisions are the mere selection of courses of action.

Choices are our conscious experience of moral or other dilemmas.

So they influence his preferences and predilections by providing him with an absolutely totalitarian, micro-controlled, repetitive environment.
