Dumbledore: And then your father did something Snape could never forgive.
Harry: What?
Dumbledore: He saved his life. <snip> I do believe he worked so hard
to protect you this year because he felt that would make him and your
father even. Then he could go back to hating your father's memory in
peace.

In a list of grievances Harry could write against Dumbledore I do not
think that would rank very high, in light of future events it seems
positively trivial. Much more important was Dumbledore raising Harry
like a pig for slaughter. In book 6 Harry asks Dumbledore if he thinks
his private lessons will help him survive, Dumbledore responds that he
certainly HOPES it will help him survive. That is not technically a
lie but it is very misleading because Dumbledore did not THINK it
would help Harry survive, he didn't think anything could do that.
Dumbledore did not bother telling Harry this of course and I believe
that would cause more resentment toward Dumbledore than anything else.
