Brutus does not feel Mark Antony poses a threat, thus he tells Cassius that killing Mark Antony will make "[the conspirators'] route appear too bloody" (line 175). According to Brutus, killing Antony is needless since he has no authority without Caesar and is "just a limb of Caesar" (line 178). Furthermore, according to Brutus, it would be better if everyone just followed Caesar's orders: "Treat his [Caesars] letters as if they were laws. Let us all swear loyalty to him." (lines 183-185) In conclusion, Brutus says killing Antony will make the conspirators' route look like it was done in a bloodbath which is not necessary because Antony has no power on his own.
