I don't know if I have to post this to take the test, but I will just
in case.
Claudius shows this because he killed his own brother just to get the
thrown and then he wouldn't even apologize for what he did. Also
Laertes because he didn't care if he had to kill Hamlet in a church,
he wanted revenge no matter what, unlike Hamlet who wouldn't kill
Claudius while he was in prayer.
