No. Link is Courageous because of the Spirit of the Hero. The Triforce just seals it. In Lorule, Ravio is not courageous because the Triforce was destroyed, and thus the Spirit of the Hero is nonexistent.
Edit: I found something new.
Um... I'mma correct you here, if you don't mind. Lorule is an opposite version of Hyrule. Hilda is naive, not wise. Ravio has cowardice, not courage. Yuga is weak and vain, not powerful - of course he merges with Ganon so I guess that's negated.
