answer:Hamlet learns that Claudius assassinated his father at the end of the first act, but does not kill Claudius until the final scene of the final act. Obviously he’s taking his time. There is also plenty of textual evidence in between to support the idea that Hamlet procrastinates (or is paralyzed by overthinking). Try looking at Hamlet’s soliloquies, in which he reasons with himself, reveals motives, etc. Also try thinking about opportunities that Hamlet fails to act on – especially when Claudius is vulnerable. I can’t be more specific than that because I don’t have the play at hand, but it’s best anyway that you do your own homework, yes? Hope this helps.
