Is Brutus Justified In Assassinating Caesar?

I think sometimes a man gets blinded by his needs .Brutus was one of the chief conspirators who were involved in assassinating Caesar. He was jealous of Caesar's popularity and  wanted to grab the power . Caesar was in his way  so he killed him with another person ,Cassius .This attempt was not a justified one and he and his fellow conspirator met there destiny when Mark Anthony ,one of Caesar's friend defeated them and hanged them to death.
