Which best explains why Anthony describes Brutus as the noblest Roman of them all

The noblest Roman of them all, according to Marc Antony, was Brutus-one of Caesar's assassins, and now a corpse at Antony's feet. The note of regret here is ironic, to say the least, because Antony raised the army which has destroyed Brutus.

Explanation:he stands up for what he believes in, risks his life for Rome, and doesn't seem to be concerned with personal gain. Yet for all of Brutus' good qualities, his troubles stem from his decision to murder a man and his misjudgment about the consequences.
