"My dad says Dumbledore is the worst thing to ever happen to Hogwarts"

I must say, this quote by Draco Malfoy is a bit on the nose and I agree with it 100%.

Dumbledore was a psychopathic idealist with questionable judgment.

Basically Dumbledore constantly endangers a bunch of innocent kids, year after year, by keeping Harry Potter in mostly unguarded situations to lure Voldemort to the campus.

What in the heck? Why is no parent concerned about this?

To make it worse, Harry Potter is a below-average student who is constantly getting in trouble due to his misconduct.

You would have thought that after the events of Cedric Diggery dying, Dumbledore would have taken more precautions...but nope!

And the guy has no teaching ethics! At the end of the year, when awarding the once-presumptuous cup to a house, he defiles it by changing the rules at the last minute so that Gryffindor can win.

And what's with the creepy device he has that allows him to go into people's memories?

Dumbledore is not a good role model, and I'm glad that Snape kills him. Snape, unlike Dumbledore, has good moral principles and seems to be the only teacher at the school actually concerned about the repeated antics of Harry Potter which always seem to lead to people getting killed or seriously injured.
