Your logic is impressive: so what is wrong with Joanne Rowling that she can't understand that what she actually wrote is NOT what she keeps telling everyone? Quite the opposite.
Dumbledore is not inherently good; he's manipulative and unjust. He makes unwarranted assumptions, he plots and schemes based on his arrogant prejudices, and blithely takes for granted that he and he alone knows what is best for everyone - the Greater Good. He's charming, I'll give him that - but when necessary, so is Tom Riddle - and his machinations against Riddle keep getting other people hurt and killed. Just because he loses his mind and puts on a ring he KNOWS is cursed, presumably in the hope of resurrecting his sister whose death he caused unintentionally, doesn't make Dumbledore any less of a selfish, inconsiderate bastard. More so, in fact, because it leads him to manipulate Severus Snape - AGAIN - into doing a horrendous, dirty job he doesn't want to do (killing the old man) with no regard for Snape's emotional state or other possible repercussions for Snape.
I don't want to get any further into a long rant about the old man's failings (or Rowling's), but I do want to say that I agree with the points you've made. Good essay!
