Morality is conditional. There is no way to determine ahead of time what the appropriate moral decision is for a given situation. A truly complex decision is woven with so many thread and contains so many competing needs that a truly right path may be too difficult to follow through or may not even exist. When we go through life, we are confronted by thousands if not millions of choices every day. Most end up being choices of no consequence. For instance, walking down the sidewalk and observing an insect on the path, the choice to step on it or not presents itself. So small is the choice that it probably doesn’t even enter the person’s mind.
Generally when we call something a choice, we speak of those moments that seem to possess potential consequences and that require conscious thought when considering it. They may be small things, like what to order off the menu or (along the same lines) what car to buy. What we call a choice are things that we stop and think about, weighing whatever considerations we feel necessary and then picking an option that seems reasonable.
