What do you fight for?

[Morsul the Dark]

Well I'll try my hand at this thread if I may.

I think a good example of someone fighting against evil vs "for good" would be Treebeard.
Treebeard in the book(Vs wishy washy movie treebeard) was very strongly for battling Saruman and called the moot to discuss it and plan.

I don't think he really ever thought too much further than the borders of his forest, though. They take out Isengard pretty handily but It isn't a campaign so much as, how to word this, Pest control? It seems Treebeard had to be pushed pretty far before coming to the conclusion battle was needed. As quickly as they subdued the tower, you could attribute that to Helm's Deep but It seems the ents could've take Isengard pretty early on had they wished.

Again though I think while He's trying to save the forest he doesn't seem to have much worry about middle earth as a whole which makes sense. The ents are of course a doomed race so why bother saving a world they won't see?

This is mostly conjecture on my part and based on memory since I haven't read the books in at least 2-3 years.
