He is justly served.
It is a poison tempered by himself.
Exchange forgiveness with me, noble Hamlet.
Mine and my father’s death come not upon thee,
Nor thine on me.

– William Shakespeare

Hamlet, Act 5, Scene 2. When Hamlet stabs Claudius with the poisoned sword and makes him drink his own cup of poisoned wine, Laertes says his death is well deserved. He signifies that he does not blame Hamlet for his or his father Polonius’ death.
