Go back and watch the end of the very first episode. Walter White is standing in his underwear recording a full confession on a camcorder to explain what went wrong (before he realizes they are going to be fine and destroys the confession).

Then go forward and watch the confession on the DVD Heisenberg gave Hank last night.

Just comparing the two confession tapes from the start and from now, you can see the incredible transformation that Walt has gone through in becoming Heisenberg.
