He Knew Exactly Who Killed His Father. So Why Did Hamlet Wait Four Acts to Act?

Have you ever known exactly what you needed to do, and exactly who you needed to do it to, and still couldn't make yourself move? Not because you were scared. Some other part of you just kept finding reasons to wait one more day.

Four hundred years ago, Shakespeare wrote an entire play about that feeling. The main character is a Danish prince named Hamlet, and he speaks the single most famous line in the English language because of it: "To be or not to be." Thug Notes, a Wisecrack literature series that runs classic novels through a thick layer of street slang, retells the whole plot and lands on one question. Hamlet knows exactly who killed his father by the end of Act 1. He still waits four more acts to do anything about it. Why?

An Uncle, a Crown, and a Ghost

In the Danish castle of Elsinore, the old king is barely in the ground before his brother Claudius marries the widowed queen, Gertrude, and takes the throne. Her son, Prince Hamlet, is furious that his mother remarried so fast.

Then the castle guards spot the old king's ghost pacing the walls at night, and they send Hamlet to go talk to it himself. The ghost tells him the truth is worse than he thought. Claudius murdered him in cold blood to steal the crown. It's on Hamlet now to get revenge.

A Play Within the Play

Meanwhile, Hamlet's girlfriend Ophelia gets warned off by both her father Polonius and her brother Laertes, who tell her Hamlet is likely to use her and toss her aside. She thanks them for the heads-up, then keeps ignoring their advice anyway. When Hamlet starts acting unhinged while he wrestles with the idea of killing Claudius, everyone around the castle just assumes he's lovesick.

Can the ghost even be trusted? Hamlet comes up with a way to test it. He stages a play that reenacts exactly how Claudius killed the old king. Watching his own crime performed on stage, Claudius bolts for the exit. Now Hamlet knows for certain the ghost wasn't lying.

One Wrong Stab, and Everything Unravels

Even with the truth confirmed, Hamlet still doesn't act. He storms into his mother's chambers to confront her, while Polonius hides behind a curtain to eavesdrop. Mother and son are mid-fight when Polonius gets startled and cries out. Hamlet, assuming it's Claudius, stabs straight through the curtain. It's Polonius who dies.

That one mistake sets off everything that follows. Laertes is enraged over his father's death. Ophelia's grip on herself falls apart entirely, and word soon comes that she has drowned. Claudius seizes the moment, arranging for Laertes to challenge Hamlet to a duel with a poison-tipped blade, and, just in case, poisoning a cup of wine as backup.

On the day of the duel, the queen drinks from the poisoned cup meant for Hamlet. Laertes and Hamlet wound each other with the poisoned blade. As Gertrude dies, Laertes, dying himself, confesses Claudius's whole plot. Hamlet kills Claudius and forces the poisoned wine down his throat too. By the end, the entire royal family is dead, and the Danish throne passes to a foreign soldier named Fortinbras.

So What Was He Waiting For?

Hamlet has the truth in hand by Act 3, and he still doesn't act until Act 5. It's one of the most argued-over puzzles in all of Shakespeare, and Thug Notes offers three explanations without picking a favorite.

Quick decode: three theories, each one going a little further than the last. The mildest one says Hamlet is simply too sensitive to survive in a world full of people who lie and scheme without blinking. Anyone else in his position would have moved already. A deeper one says some scholars believe Hamlet's feelings for his mother run past an ordinary mother-son bond, deep enough that he can't bring himself to kill a man for doing the exact thing Hamlet's own buried instincts want: getting rid of the father and having the mother to himself. Psychologists later gave this idea a name, the Oedipal Complex. The sharpest theory says he isn't stalling on whether to kill at all. He's resisting the whole rotten system. The kingdom is built on lies and betrayal from the ground up, and killing Claudius alone wouldn't fix that. His hesitation is him working out how to tear the whole thing down, not just swap out who's sitting on the throne.

Which one sounds right to you? Maybe a little of all three?

Respectable on the Surface, Rotten Underneath

When Hamlet tears into his mother in Act 3, he talks about "ulcerous places" and "blisters" on the body and soul. By Act 5, the gravedigger scene describes "pocky corpses." Thug Notes threads these images into one point: this is exactly what the play captures about being modern. No fixed code of conduct to fall back on, stuck instead with what it calls a "divided mind and will." In other words, if you've ever known someone who looked harmless on the outside and never once was underneath, this four-hundred-year-old play already had that type figured out.

"To Be or Not to Be": Two Different Questions

The most famous line in the play actually carries two different readings. One take is that Hamlet is literally weighing whether to keep living. The other reads it as a choice between two paths: the Christian ideal of denying the self and holding back, or picking up a blade and settling the score by force. Underneath the same eleven words sit two entirely different ways of facing a life.

Behind-the-Scenes Trivia

• Sparky Sweets, PhD, the host, is dressed in a sharp suit and speaks almost entirely in street slang. When Hamlet finally forces Claudius to drink the poisoned wine, Sparky throws in one line: "Elizabethan haterade. Gotta have it." The bloodiest moment in the whole play gets compressed into a joke.
• The video nicknames Hamlet "Hammy," used right when he storms into his mother's chambers.
• Unlike most Thug Notes episodes, which usually land on one clear verdict, this one refuses to pick a favorite among its three delay theories and just hands all three to the audience.
• This was Thug Notes' first Shakespeare episode, and it picked the hardest one to summarize. It signs off with one line: "Looks like Ol' Willy's gone and made Hamlets of us all," because Shakespeare never actually answers whether the ghost can be trusted, whether Gertrude knew all along, or whether Hamlet's madness ever stopped being an act.
• The whole episode runs eight minutes, so the most famous stabbing in the play, Polonius dying behind the curtain, gets one line and no follow-up on how Hamlet reacts to realizing he killed the wrong man. Eight minutes only stretches so far.
