"It is our choices, Harry, that show who we truly are, far more than our abilities."

- Albus Dumbledore

Neville to the Dark Lord in Deathly Hollows:

It doesn't matter that Harry's gone. People die every day , friends, family. Yeah, we lost Harry tonight. He's still with us , in here(heart). So's Fred,Remus,Tonks,all of them. They didn't die in vain. But you will. Because you're wrong! Harry's heart did beat for us. For all of us. It's not over!

And also Snape: +after all this time? _ALWAYS

My favourite quote is "there is no good or evil there is only power and those too weak to seek it"

And the quote that you said is actually said by Phineas Nigellus in the book tho but in the movie Kingsley said that

That's right. Now, if you two dont mind i am going to bed before either of you come up with another clever idea to get us killed, or worse Expelled

"ALWAYS" -Severus Tobias Kalovan Snape-

"Really, Hagrid, if you are holding out for universal popularity, I’m afraid you will be in this cabin for a very long time,”

--Albus Dumbledore
