Elizabeth Feodorovna, a German princess, married the younger brother of Tsar Alexander III of Russia. As Grand Duchess, she embraced her new culture and converted to the Orthodox faith. Her sister married Tsar Nicholas II. After her husband was murdered she forgave his assassin.

You can’t forgive on behalf of someone else.

She did not forgive on behalf of her husband but for her own loss.

Forgiving any murder but your own is hybris.
