In T.S. Eliot's Murder in the Cathedral, St. Thomas a Beckett responds to his tempters, especially addressing the suggestions of the fourth:
Now is my way clear, now is the meaning plain:
Temptation shall not come in this kind again.
The last temptation is the greatest treason:
To do the right deed for the wrong reason.
With these words he receives peace and chooses not to become a martyr, but to accept the inevitability of death, as we all must.
