Why do you think Arthur choose to forgive them rather than punish them once he is crowned king?

By forgiving, he seeks to heal the divisions within his kingdom and foster loyalty among his subjects, demonstrating that leadership is rooted in compassion rather than vengeance. This act of mercy also sets a precedent for his rule, emphasizing that strength lies in forgiveness and the ability to move forward together.
