Was Hamlet Mad or Mad?

Hamlet's state of mind is very debatable thoughout the play. His sanity has been questioned for hundreds of years, and my belief is that Hamlet was sane. The play begins with Hamlet grieving over his dead father. He is also troubled by his mother's quick and incestuous remarriage to his uncle, and the appearance of a ghost that looks like his deceased father. In ACT I, Scene V, Hamlet returns from talking to the ghost. …

…would have died without caring who took the throne of Denmark. He proved his sanity again when he asked Horatio to carry out his two dying wishes. He showed that he cared about his country by selecting Fortinbras to take over. And he wanted his actions to be justified so the people would understand and still love him. Hamlet wasn't crazy, his actions were just part of one big plan to get his father's revenge.
