some quotes from julius ceasar?

Question

i need some quotes that show that violence and bloodshed do not have morally good results.

Answer 1

I assume you mean the play "Julius Caesar" and not the words of Roman emperor.

"The abuse of greatness is when it disjoins
Remorse from power." Ac. II, sc. i

"... Great Caesar fell.
O! What a fall was there, my countrymen;
Then I, and you, and all of us fell down,
Whilst bloody treason flourished over us." Ac III, sc. ii

Answer 2

"Et tu, Brute?" (Even you, Brutus?) this expression has come down in history to mean the ultimate betrayal by one's closest friend.
