Professor McGonagall (for keeping the students safe)
Mrs. Weasley for killing the world's most dangerous fanatic
Any Slytherin who fought
Neville for deadening the fear factor da standing up to Voldemort in front of everyone
And Snape should get a major memorial - it was he, Dumbledore, and Harry who brought Voldemort down. Also anyone who was killed in that battle... Fred, Lupin...
Now ask who should be disgraced... I think Umbridge should be burned to death publicly. I would've detto Bellatrix too if she were alive - prison is fitting enough for the others.
