Read the excerpt from act 4, scene 2, of The Tragedy of Julius Caesar.

[BRUTUS.] He is not doubted—A word, Lucillius.
How he received you let me be resolved.

LUCILLIUS. With courtesy and with respect enough,
But not with such familiar instances,
Nor with such free and friendly conference,
As he hath used of old.

BRUTUS. Thou hast described
A hot friend cooling. Ever note, Lucillius:
When love begins to sicken and decay
It useth an enforcèd ceremony.
There are no tricks in plain and simple faith;
But hollow men, like horses hot at hand,
Make gallant show and promise of their mettle;
But when they should endure the bloody spur,
They fall their crests and, like deceitful jades,
Sink in the trial.

Which central idea is reflected in this passage?

It is the fate of Brutus and Cassius to rule Rome together after winning the battle against Antony and Cassius.
The friendship and confidence between Cassius and Brutus is deteriorating.
Brutus says he is sinking under the burden of leadership and needs help from Cassius.
Lucillius explains the need for compromise between Brutus and Antony in order to survive the battle.

Albeit the play is named Julius Caesar, Brutus talks multiple occasions however many lines as the title character, and the central mental show of the play centers around Brutus.

Destiny versus Free Will. Julius Caesar brings up many issues about the power of destiny in life versus the limit with respect to freedom of thought.

Cassius won't acknowledge Caesar's rising power and considers a confidence in destiny to be just a type of resignation or weakness.

Desirous backstabbers persuade Caesar's companion Brutus to join their death plot against Caesar. To prevent Caesar from acquiring an excess of force, Brutus and the backstabbers kill him on the Ides of March. Mark Antony drives the schemers out of Rome and faces them in a conflict.

The central idea of the play, thought about strategically, is the rot of republicanism in Rome and the ascent of Caesarism. In the First Scene the general population give oblivious proof of the developing soul of government. This they show when they shout out in the Third Act Let him be Caesar.
