Did D'dore Hang onto "For the Greater Good" All His LIfe?

YES

Dumbledore may have not continued thinking of "wizard dominance being for the muggles' own good," but the idea did continue in his life (DH, pg357, U.S paperback). When our beloved D'dore and Grindlewald were buddy buddy, he thought that "any harm done would be repaid a hundredfold in benefits for wizards." When he neglected to tell Harry the whole truth so he could be a lamb for slaughter, he thought the same.

Even with all of the pain in his life, he was a champion for love. However, he still can not trust. Many readers think that Harry would have still made the sacrifice willingly if he had known the details. However, it seems that D'dore did not trust anyone enough to put all his information "eggs" in one basket. So instead, Snape had some, Harry had some, the Order had a few, and even Grindlewald got to have some of Dumbledore's thoughts and feelings entrusted to him. But Dumbledore would not trust anyone totally.

Point blank: Dumbledore should practice what he preaches. Love includes Trust, total trust.

NO

Dumbledore knew that he had been wrong in his youth. Befriending Grindelwald brought about horrible things in his life, and he gave up on the Hitler-like thoughts right away.

Dumbledore did not tell Harry everything he suspected because Harry was already burdened enough, whatever the reasons he gives at Kings Cross. The same can be said with Snape, or the Order. Knowing all of Dumbledore's thoughts and feelings would be overwhelming. Even D'dore has to filter himself with his Pensieve, as we see several times in the series.

Harry had to learn some things on his own, not just have someone tell him, "oh, by the way, you have to willingly die." Harry can not complete his hero story without the quest to understand life, and ultimately leave it behind. Also, Dumbledore was worried that his "hot head might dominate...[his]...good heart" and that he would try to use the Hallows as he did.

Bottom Line: Dumbledore shows his love by not telling Harry everything; it has nothing to do with the greater good.

MY HUMBLE OPINION

I will admit that after reading DH, I was none too happy with my favorite headmaster. It seemed to me that the greater good had never really left D'dore after all. The way he had kept Harry in the dark seemed like an old man's failing. However, looking at it from as non-emotional a standpoint as possible, I can see the other side of the coin as well. Dumbledore was trying to protect Harry from his mistakes and still help him as much as possible. My opinion, Dumbledore was simply doing the best he could, which was neither horrible or great.
