There are several lessons about life that the audience should learn from the life of Julius Caesar and his play which dramatizes the important parts of Julius Caesar’s life. One important life lesson to learn is to watch out for your friends. You really do not know your friends as much as you think you do. Instead, you should be careful. You can trust your friends, but see if you can read them when something goes wrong.
Also, another life lesson is to watch yourself. You may be gaining too much power in your job or with your co-workers. You should understand that having too much power may turn people against you. Therefore, it is best to not be power-hungry and abuse your power.
There are many life lessons in the Julius Caesar play. One of them is idealism. Brutus fears that Caesar is too power hungry, and he doesn't want him to destroy the republic. It is Brutus' idealism that ultimately causes his downfall. Another lesson is ambition and conflict. The ambitions of Cassius and Caesar led to their downfall. Great ambition leads to great conflict.
There is also a universal theme of betrayal from multiple perspectives. Brutus betrayed Caesar and plotted against him. Cassius was the perpetrator of Caesar's murder. Also, there is a lesson in the idea that hunger for power can lead to one's demise. Also, our fates are controlled by natural order, and we cannot change or disrupt this because it can lead to disastrous consequences. Ambition destroyed those who conspired against Caesar.
