Please help me, this is for Shakespear's play Julius Caesar..I answered them but need more insight?

Brutus let Antony live. In doing so, he allowed the creation of a formidable opponent. Of the two, Antony is the better soldier and has more practical knowledge. He is more experienced and knows how to deal with extreme situations. Antony is also resourceful. He gathers a large army, and along with Octavius Caesar, gets ready to attack Brutus and Cius. Even though Cius is as good as Antony, his opinions and decisions are overruled by Brutus. So, all this together results in the defeat and deaths of Brutus and Cius.
