A compulsion refers to a "forced obligation." This means that a person has the duty or responsibility to act a certain way regardless of whether they want to do so or not. Moreover, implicit refers to a situation that is understood, but might not be expressed. An example of this is the responsibility to rescue someone who is in danger. Although neither party can express their preference, there is an implicit agreement that corresponds to the responsibilities of the rescuer.
