A Hufflepuff will always stand to fight for what is right—not because it is the brave thing to do, not because it is the intelligent thing to do, not because it is the great thing to do, but because it is the right thing to do.
I'm not to sure about the "stand and fight" part, because that's what Gryffindors are known for, not Hufflepuffs. A Hufflepuff can be expected to do what's right, and to advocate for what's right, but can't be counted upon to fight for it.
Whether a Gryffindor will stand and fight for the right reasons, or for bad reasons, is entirely individual, and dependent on traits not evaluated as necessary to join Gryffindor.
Do I sound like a Ravenclaw yet?
