I don't think LOTR supports your case at all.

I guess Frodo is the main hero. He is left the ring and is forced to leave his home. His shortcut through the old forest nearly kills the entire party until he's rescued by Tom Bombadil. He then nearly dies in the barrow until he's rescued again by Tom.

He doesn't know what to do at Bree until Strider helps him. He succumbs to the temptation to put on the ring at Weathertop and then becomes a burden to the rest until Rivendell.

He doesn't know how to get into Mordor until Gollum helps him. He gets stung by Shelob and captured by orcs and it's only because Sam took the ring that the whole mission isn't blown.

He runs out of strength climbing Mount Doom and again he's saved by Sam carrying him. When he gets to the Cracks of Doom he fails to destroy the ring and is saved by Gollum attacking him.

And even back in the Shire, he can't settle and ends up leaving.

He's just not a very heroic figure and more affected by circumstance, continually requiring rescue. Maybe a bit more like Arthur Dent than it first appears. :)

Indeed, I think what Frodo would like most is for it all to just end. Exactly as Adams said of Dent when discussing his motivations/desires with Hollywood producers.

I disagree, he is extremely courageous. The fact that he does it not out of some sense of innate heroism and adventuring desire makes him even greater. He's not there due to anything else other than is sense of right and wrong.

There are several heroes in LOTR:

- The more "heroic" archetype of Aragorn

- The flawed character of Boromir that atones himself for his sins with one last heroic stand

- The unwilling but ultimately acceptance of Frodo

- The more laidback silly courage of Merry and Piping

- The devoted courage of Sam

- Even Galdalf, when he faces that fiery beast (I don't remember the name right now) and Sauruman.

- And there are many side characters that also fit the role (like the Rohirim)

It is truly a tale full or heroes and several acts of great courage. Many of them might not have gotten into it willingly, but they surely took on the role seriously and honorably.
