Hamlet's Dilemma

I think it was a smart decision of Hamlet to not kill Claudius. Claudius was in the middle of praying for fogiveness. For Hamlet to have killed Claudius in the middle of this act he would have definitely been sent straight to hell while Claudius went to heaven. It was better for him to wait for better timing. Plus, killing someone with a sword is an easy way to get caught. Poisoning him would be an easy get away and would give Claudius his justice.
