Which explanation provides the best evidence to support the interpretation that Brutus is a patriot?

Brutus was a patriot because he loved Rome so much he had killed the man he loved. But he loved Caeser less than he loved Rome. Brutus perceived Caeser as a tyrant who would harm Rome. The irony is that by killing Caeser in his love for Rome, Brutus unleashed a brutal civil war as well as many unhonorable actions.
