hmm, how about:
- Dumbles letting Snape get away with blatant favoritism for his house/make up reasons to penalize the other houses (especially Griffendor)
- Snape's hatred of Potter being so mouth-frothingly intense that he'll blame anything and everything on Potter even when there's no way Potter could have been involved.
- Similarly Snape's hatred leading him to badmoth Potter even when such accusations merely make Snape look stupid.
- Dumbledore's 'greater good' being nothing more than his own legacy/fame/ego, and him being quite willing to sacrifice others to his own benefit
- Timeturners being available to any top tier student
Edit: geeze, I left a lot of typos in this post
