This is getting really, really good! You HAVE to write more... The world will be a bit sader if you don't finish this story! I love it! :D
Your story is pretty good so far, and I've upoed my standards massivly after reading the impressivly great story that I think is the one you got the idea of harry's dad throwing money away from. *Chuckles* A tragedy that the autor gave up on the sequel. I can see how it could have inspired you, your story holds a bit of the same greatness thus far.

Please keep up the good writing. I really do love Evil Harry. *Chuckles* And Voldermort, being evil, arrogant and in his Tom Riddle form is incredibly hot! *Grins*

Canon-Lupin was originally one of my favorite characters in the 3rd book. But then I reread the book(s) and thought more carefully about the characters. I think you have a good handle on his character. He doesn't stand up to his friends when they bully others (to be fair a lot of people don't have that inner strenght most of the time) but he is quick to try to guilt Harry into behaving "properly".
I was sad with the portrayal of Draco Malfoy. I know he was a bit of a whiny git in the beginning of the books so you weren't completely off. But I was still sad to see Harry humilate him in the great hall when you had started to set Draco up as a confussed but redeemable boy. I find it hard to see any reconciliation as Draco's wounded pride would set up a road block. Of course, this isn't a H/D story so I guess it's not as important here, but I was hoping they'd be friends at least. Harry will need someone his age to relate to... even if he is more advanced than most people his age.
All in all, I think you did a good job for this kind of story. Often dark!Harry has the sudden revelation and Dumbledore is super correupt, Ron and/or Hermione are terrible friends that are just using him, and Harry starts killing and torturing people left and right. Your story is more believable. Dumbledore is manipulative but in a way that's believable that he could get away with. Your Ron and Hermione aren't good friends but they aren't the most terrible people either. And it is a slow but believable progression for Harry to make it to the "dark" side. I also like how you addressed Dumbledore's various titles. I don't think I've seen that in a fic before.
I look forward to reading the sequel.
