Snapedom

Sorry Oryx, I don't understand your point here. Dumbledore left the sword to Harry in his will. Morally the sword belonged to Harry, and he already had won it under conditions of valour. I think throwing the sword into the pond was an error on Snape's part. He just didn't plan very well when he didn't have Dumbledore to advise him. The portrait didn't have the true Dumbledore's depth of understanding. But it's a portrait and all portraits can do is echo in a faint manner what the person who is in it was like. They seem to know what that person knew up till the time of creation, but they cannot know outside of that.
Harry never went down a Labyrinth. He went down to the Chamber of Secrets and he went to where the Philosopher's Stone was hidden, that is true. It is also true that Dumbledore realised that Harry would need to gain practical experience in dealing with Voldemort. Dumbledore knew that Harry would need to learn fast and learn young. That knowledge could not be taught in a classroom. I think Harry learnt very fast and very young. This was a necessity as Harry had been marked by Voldemort himself as the only one who could defeat him. I'm not to sure what Snape had to do with that, to tell the truth. I know he told Voldemort the Prophecy that targeted the children who were due to be born at the end of July, but he didn't tell Voldemort who to pick.
Harry is very independent and fearless, he has to be to defeat Voldemort.
Do you mean the Maze in GOF by the Labyrinth. Dumbledore had nothing to do with Harry entering the Maze. That was Barty Crouch Jr's plan. Dumbledore had no choice in the matter, Harry had to play or die.
