As we see in the end, Mr. Hyde was found dead in Dr. Jekyll's room. As Mr. Hyde had committed some serious evil acts in the past, he could not be forgiven for his acts. In the end, the chemicals which Dr. Jekyll was taking for converting into Mr. Hyde became the reason for his death. Dr. Jekyll could not take up the guilt of the evil acts he had committed as Mr. Hyde.
The death of Mr. Hyde from his own hands proved that God will always prevail over evil and there is always an end to evil.
