In Act III, Scene I of the play Julius Caesar, when the conspirators are approached by Mark Antony after they have assassinated Caesar, they assure him that they do not wish to kill him and ask him to wait until they have gained control of the situation to be satisfied of the legitimacy of their motives. Antony responds with the following:
I doubt not of your wisdom.
Let each man render me his bloody hand.
First, Marcus Brutus, will I shake with you;
Next, Caius Cassius, do I take your hand;
Now, Decius Brutus, yours; now yours, Metellus;
Yours, Cinna; and, my valiant Casca, yours.
Though last, not least in love, yours, good Trebonius.
Gentlemen all — Alas, what shall I say?
My credit now stands on such slippery ground
That one of two bad ways you must conceit me,
Either a coward or a flatterer.
That I did love thee, Caesar, O, ’tis true!
If then thy spirit look upon us now,
Shall it not grieve thee dearer than thy death
To see thy Antony making his peace,
Shaking the bloody fingers of thy foes,
Most noble! in the presence of thy corse?
Had I as many eyes as thou hast wounds,
Weeping as fast as they stream forth thy blood,
It would become me better than to close
In terms of friendship with thine enemies.
Pardon me, Julius! Here wast thou bayed, brave
Here didst thou fall; and here thy hunters stand,
Signed in thy spoil, and crimsoned in thy lethe.
O world, thou wast the forest to this hart;
And this indeed, O world, the heart of thee!
How like a deer, stroken by many princes,
Dost thou here lie!
Now I know that Antony plans to manipulate them into thinking that he is on their side, but is the section of the speech starting from "That I did love thee..." part of the manipulation (maybe to appear more credible?) or is he simply overcome by genuine emotion there and speaking from his heart?
