This was the most unkindest cut of all;
For when the noble Caesar saw him stab,
Ingratitude, more strong than traitors' arms,
Quite vanquish'd him : then burst his mighty heart;
(a) Who speaks these words?
(b) Whose ingratitude was he referring to?
(c) Why did it break Caesar's heart?
a) These words are spoken by Antony.
b) He was referring to the ingratitude of Brutus.
c) Caesar thought Brutus was his close friend and confidant. Hence, Brutus’ cut was the unkindest of them all.
