What's good about the good guys?

We've heard a lot of complaints lately about the good guys,
particularly Dumbledore. I'd like to turn that around and ask those
who admire those characters and even those who are disappointed in
them to consider what's good about the good guys, particularly HRH and
Dumbledore but also anybody who qualifies as "good" by virtue of
ending up on the right side of the battle.

For example, I lost most of my respect and all of my affection for
McGonagall in DH. Can someone help me to get them back? I couldn't
even enjoy the moment when she herede all those desks onto the
battlefield because I was too upset by her dealings with Snape and the
Slytherins and by her use of the Imperius Curse when surely a
Confundus Charm or Expelliarmus would have done the trick.

I don't think anyone needs help admiring Neville (hooray for Nagini's
Bane!), but I'd like us to think about ways in which the good guys are
genuinely admirable in DH or how they've grown and developed over the
series. 

If you want to talk about what's good about the bad guys or what's bad
about the good guys, please use a different thread. (I'm counting
Snape and Slughorn as good guys because they fought against Voldemort.
And, love him or hate him, I'm counting that old Machiavellian
puppetmaster DD as a good guy, too. Let's think about how things would
have been different had he not been involved in Harry's life and the
running of Hogwarts (or getting Snape to change sides).

acting through portraits (Sirius Black counts, too)
