The turning point of the tradegy is shown in this part:
"Now might I do it pat, now he is praying;And now I'll do't—and so he goes to heaven,And so am I reveng'd. That would be scann'd:A villain kills my father; and for thatI, his sole son, do this same villain sendTo HeavenO, this is hire and salary, not revenge." These lines reflect internal conflict of Hamlet who says that he wants to commit a revenge. But he stuck with doubts because he starts to realize that the feeling of completed revenge won't bring his father back to life.
