Responsibility is an abstract concept. As is the case with other abstractions, "responsibility" does not exist in nature. It is a creation of the mind. And, like other such creations, it is a concept which must be learned.

Of course, we are then drawn to ask, "Is a person "responsible" if he has not been taught the meaning of responsibility?"

In the sense in which we are presently employing the word, the answer is clearly "yes".

No one else made the individual's decision, or carried out the specific action that the individual him or her self engaged in.

It is quite possible of course, that others indeed urged the individual to commit the action. They are then responsible for having urged, but the individual is still responsible for those decisions and actions he or she actually committed.

Each person is responsible, and accountable, for his or her particular degree of participation.

But suppose that the individual was compelled by others, who literally forced him or her to do the deed?

In that case, the responsibility for compulsion must be placed upon those who compelled.
