What is dimmesdale tempted to do as he returns to his room ? Why?

"Dimmesdale returns to town thoroughly aware of having a new perception of life. He has much more energy than when he left only two days earlier, and everything looks different to him. Three times in a row he is approached by various people, and he struggles not to utter blasphemy. He is even tempted to teach dirty words to a group of small Puritan children."

This is a reaction to the freedom and passion he became aware of in the woods with Hester. Dimmesdale is so full of emotion that he's reasy to act in complete oppostion to everthing he believes.
