Why did the mob kill an innocent man named cinna?

In the play "Julius Caesar" by William Shakespeare, the mob mistakenly kills Cinna the Poet because they are inflamed with anger and seeking retribution after Caesar's assassination. They believe that Cinna's name, which is the same as one of the conspirators, justifies their violent actions. The mob's frenzy and lack of reason highlight the chaos and brutality that can arise from mob mentality. Ultimately, Cinna's death serves as a tragic reminder of the consequences of unchecked rage and misunderstanding.
