INTENT?

In Shakespeare's play "Hamlet", one of the main themes we see is vengeance. Prince Hamlet is determined to gain revenge against his Uncle, Claudius, for the gruesome murder he committed against his father. Although Hamlet swore to his father that he would commit the act, we see him hesitate at times, postponing it further and further. Such a decision makes us wonder, was Hamlet truly intent on killing his uncle? Did he have it in him from the beginning to commit such treachery, or did he understand that two rights wouldn't make a right?
If we look at the world today, we know that most people wouldn't go around killing their enemies, as a form of revenge. If this were to happen, our population would dwindle drastically. However, back then, things were extremely different. Everything tended to be far more dramatic. Murder seemed to be the only answer, a means to an end.
Hamlet on the other hand, stands out among the rest. We see that he had several chances to commit the act against his Uncle, but let them pass by, creating excuses for himself each time. It makes us wonder if he really had the intent all along, or was he just playing an act the whole time?
It's true, that in the end, Hamlet did end up killing his Uncle. But, was it simply out of rage? It was a time of weakness for Hamlet...he just saw his mother get murdered, and he himself was dying at the time. It's a question to keep in mind: Did Hamlet truly intend on killing his Uncle or was he more civilized, as we are today, and tried to avoid the act as much as possible.
