Seems both are true. Translation below taken from Columbia University’s website.

Within each mouth—he used it like a grinder—
with gnashing teeth he tore to bits a sinner,
so that he brought much pain to three at once.

The forward sinner found that biting nothing
when matched against the clawing, for at times
his back was stripped completely of its hide.

“That soul up there who has to suffer most,”
my master said: “Judas Iscariot—
his head inside, he jerks his legs without.

Of those two others, with their heads beneath,
the one who hangs from that black snout is Brutus—
see how he writhes and does not say a word!

That other, who seems so robust, is Cassius.
But night is come again, and it is time
for us to leave; we have seen everything.”

Brutus was optimate scum and deserved worse than he got

I don’t know what he got, but yes.
