Because, I was silly enough to check ...eh, other sites, and found ...eh ...some people (no comment on how smart I think they are) comparing Voldemort and Dumbledore and making the point that they were almost the same thing, and I need some real, intelligent discussion where no one brings up the Bible or Hitler unless you're doing it to actually make a point and not to fill up space so your post is longer.
We won't mention the fact that Voldemort killed a lot of people for no good reason at all, since that doesn't seem to be important in the discussion.

So, let's just stick with the fact that we found out in DH that Dumbledore had a plan for Harry, from the beginning. Does that affect your view of him, and how?
Yes, I'm asking if you think he's secretly evil.

In what other ways can we compare him to Voldemort? In fact, in what way, any way, can we compare the two?
For me, it's rather simple. He's the Obi-Wan type, if you will. Sure, he's not perfect, but he really cared about the hero, and, in the end, everything he did was for a good reason. And, Obi-Wan is my favorite SW character.
