Did Caesar about the assassination and why he reacted this way? Plutarch reports that the denunciation of Artemidorus, according to Appian, denunciations were several. Moreover, the behavior of Caesar shows that if he did not know the details of urgent conspiracy, that the overall situation was understood clearly enough. As reported by Appian, a dictator openly complained about unjust accusations and intent to kill him. If Caesar decided to reveal the plot and start fighting it, no doubt he would be able to eliminate it.
Considering the acts of great men, we see the same paradox. It turns out that they had many opportunities to avoid their fate. Socrates could have avoided the death sentence, using a speech written by Lesiem, or formally repented before his judges, and after conviction he could run away or off with rich friends. Jesus knew about the betrayal and his future fate. However, both chose to become victims, in doing so, probably because the other option would force them to depart from their principles and lose all or too much. Caesar had other opportunities but they were all unacceptable. (Caesar was accused that he wants to become king and feared a repetition sultanskoy dictatorship, which brought mass terror, proscription, and, eventually, civil war. Caesar himself has repeatedly rejected such accusations and in General was not inclined to punish his enemies with death, preferring generously to pardon them). The massacre of the conspirators only "confirmed" accusations of tyranny, the other measures as the strengthening of protection or cancellation of the Senate meeting was the palliative and also would mean a departure from the principle. On offer again to take out the guard who was with him during the Spanish campaign, Caesar said that the guards "sign someone who lives in constant fear." "Republican idea" was a terrible enemy, and martyrs was one of her guns. Caesar could remember about Cato or Pompey. Now he found himself in this position.
Fear was not the fact that he was also characteristic of Suetonius reports his words: "it is better to meet danger than to fear her entire life." Caesar possessed rare courage. He has not betrayed its principles, as a young man, refusing to obey the orders of sulla (sulla forced Caesar to divorce his wife. Caesar refused, which was introduced in the proscription lists). Then it was still to come, and live, of course, very desirable. He could not betray himself now when it was already won.
In doing so, as did Caesar truly gained immortality!
