Natural or poetic justice in The Inchcape Rock

Yes, it is proved time and again in the human history that the evil doer digs a pit for others but falls into the same. This is, surely, a form of natural justice. In the poem The Inchcape Rock the Abbot placed a bell on the rock to save people, but the rover cut it down to fulfill his ill-desires. So, it was almost on the cards that he himself will eventually be a victim of his own deed. The poet has the same message to convey to the readers. The rover’s fall in the end serves as a poetic justice as well as what may be called a natural justice.
