Rav Eliyahu Dessler wrote a "phenomenal essay on bechira" (Michtav MeEliyahu, Vol. 1, pp. 111-116).In this essay,Rav Dessler describes how the "nekudas habechirah - the point of free choice" is different for different people and in different situations. He explains that bechira is not a theoretical concept that can be applied to any circumstance where a person can hypothetically choose between two options. Rather, it only applies to moral conflicts where the two opposing forces are of approximately equal strength, the person is aware of the internal conflict, and he makes a conscious decision in one direction. When a person does something over which he does not experience conscious conflict, or if the compelling force on one side is significantly stronger than the other, the fact that he is theoretically able to decide either way does not qualify his act as an expression of bechira.
