Answer:
Laertes resolves to act and get revenge immediately for his father while Hamlet cannot decide or act.

Laertes and Hamlet have one thing in common: they both lose their fathers in the play. However, their reaction is very different. Hamlet, even after the confirmation of the ghost of his father, he hesitates and thinks a lot about who is to blame, and what he should do about it. Whereas Laertes, as soon as he finds out about the death of his father he decides to revenge and he actually does something.
