In the story Hamlet we have a young man who is seeking revenge for the death of his father. The person who was responsible for the death of Hamlet's father was Claudius. Hamlet had opportunities to kill Claudius, and even in the end, when he was most assuredly going to put an end to Claudius' life, he hesitated. There is much speculation as to why Hamlet hesitated, and why he didn't just kill Claudius as quickly as possible. Hamlet did so in order to ensure he did it right and that it was a righteous killing, and not one based on rage and emotion. .
Hamlet had every reason to be viciously angry with Claudius for he was responsible for the death of Hamlet's father. Hamlet, throughout almost the entire work, was completely dedicated to the reality of killing Claudius. But, he studied himself, he studied the reasons behind the vengeful thinking, and he investigated all the information that clearly supported the fact that Claudius murdered his father. Now, Hamlet knew this, but he was a good man and needed to have irrefutable proof if he was to kill Claudius in any state of righteousness. .
Hamlet was a good man. This does not mean that he was perfect, nor does it mean that he was incredibly righteous in every aspect nor did he perhaps always do things in the manner they should be done. But, he was a good man because he always examined what it was he was doing, or what he was planning. He examined these things so as to ensure that he went about vengeance in the most righteous manner possible for him. It was not merely a murder for revenge, but a murder for the land and for the people. It was not for Hamlet alone, but for the society that had been harmed by the existence and the actions of Claudius. Hamlet understood this aspect, and needed all his time of investigation in order to clearly establish his reasoning.
One particular concern involved with performing his vengeance in a righteous manner, according to Moore, is that which adheres to stipulations in the Bible.
