What conclusion does Hamlet reach, or what does Hamlet realize, over the course of this speech?

He must assassinate claudis and avenge his father's death.

Explanation:

He is a deep thinker and realizes that he has been impulsive in the past, but not realistic. Now, he must do what needs to be done. No more wondering about what he should do. Death must come to Claudis. He actually thinks he will "get well" in his head if he does this. maybe he is not crazy, but just so depressed and feels responsible to avenge his father.
