Hamlet experiences a great deal of internal change over the course of the play. For one, he loses his fear of death: in the beginning, that fear was so crippling that it stopped him from committing suicide, but by the end, he has come to terms with death. He also undergoes a moral change in that he is more willing to overlook his own crimes. Hamlet has an acute sense of right and wrong that is associated with what religion has taught him, but he increasingly disregards that sense and justifies his crimes of murder and deception with the excuse that he is trying to get revenge on another murderer, Claudius.
