Though I am usually a rather indecisive person, this answer doesn't take me a second's hesitation:
Faramir!
For all the reasons that
Mithalwen gave.
And I think his most striking character trait is his extraordinary empathy .
(I am speaking of Book- Faramir, of course! And in my imagination he looks like Anke Eissmann portrays him.)
(btw I love the beautiful verses by Yeats you gave, Mithalwen!)
