Yes, indeed, it is very brave, / that I, the son of the murdered dear, / driven to my vengeance by heaven and hell, / must, like a whore, open my heart with words / And swearing very foolishly, / A scullion boy! Shame, foh! -Of my brain” (2.2.585-590). Here Hamlet himself reveals that he has thought too much about what needs to be done instead of acting on what should be done. In fact, Hamlet continues to insult himself because of how upset he is by his own actions of thinking and speaking instead of simply doing what needs to be done, and killing Claudius. It seems that Hamlet is also trying to convince himself that he just has to do it, but he fails when he starts questioning and insulting himself because by allowing himself to question his behavior he has already returned to his own way of thinking. Hamlet tries to break his nature here by reflecting on why he hasn't done anything and cursing himself for not having acted yet. Hamlet fails his attempts as soon as he begins them because with this reflection if his behavior Hamlet has already returned to his ways of thinking and wondered why he was such a thinker. By trying to overcome his nature using his normal method, Hamlet reveals that his true nature is to be a thinker because even when he tries to convince himself to act another way he can't stop his analysis of possibilities..
