Why is hamlet able to act in scene 4 but not in scene 3? what does this tell readers and viewers about hamlet’s character?

In scene 3, Claudius is praying.  Hamlet worries that if he kills him while he prays, he might go to heaven.  In scene 4, polonius(mistaken for closed is not praying) is not praying, so hamlet does not have this fear.
