Hamlet was NOT a ditherer or "a man who couldn't make up his mind." THAT was how he was portrayed in the Laurence Olivier film. It is NOT how the play portrays Hamlet.

"To be or not to be....": a musing on suicide, which he decides against.

"Now would I do it pat...": and decides not to kill the King while the King is on his knees praying and may go to heaven, but to kill him when he is in his "incestuous bed" or in some other situation that will send his soul straight to Hell.

Just to cite two places cited as evidence for an indecisive Hamlet.

A student, Hamlet is questioning and musing, yes...but definitely NOT indecisive.
