La clemenza di Tito
He decides to send for Sextus first, trying to get further details about the plot. Sextus takes all the guilt on himself and says he deserves death, so Titus tells him he shall have death,  and sends him away. But after a lot of painful thinking, Titus tears up the execution papers for Sextus and decides that, if the world wants to accuse him (Titus) of anything, then people can say that he allowed too much mercy, insteady of saying that he always wanted revenge.
