HBP theory

Hi everyone. It's my first post so be nice.
Looking at my HP books on the shelf it just came to me. Sorry if
I'm not good to explain it, but try to follow my thought.
I'll be very synthetic:

1) Harry Potter and Philosopher Stone
2) Harry Potter and Chamber of Secrets
3) Harry Potter and Prisoner of Azkaban
4) Harry Potter and Goblet of Fire
5) Harry Potter and The Order of Phoenix
6) Harry Potter and The Half Blood Prince
7) Harry Potter and ?

a) Philosopher Stone I always consider it as a positive thing. 
At least I suppose that it has been made for the good cause if used 
properly.

b) Chamber of Secrets  made by Slytherin used by Voldemort 
definitely a negative place

c) Prisoner of Azkaban synonym for Sirius. Even though we were made 
to believe that he was a traitor, murderer and Voldemort "best 
friend" at the end we found out that he was/is a positive
character

d) Goblet of Fire at first sight just an impressive magic object, but 
it was used against Harry so for me is a negative thing

e) The Order of Phoenix in a few words: a positive organization 
that suppose to fight against evil.

Did anyone notice this pattern? So, according to this HBP should be a 
negative character? I'm not going to discuss here who he mite be,
but can we think about him as a negative character and in that case 
eliminate some "suspects"? Any thoughts?
