what might hamets tragic flaw be?

Hamlet ruminates about the evil nature of man consuming him with just a few drops of "dram of evil". Then Hamlet ruminates about the nature of evil and the small details that define evil. Will Hamlet ever stop thinking? Hamlet indulges in his tragic flaw of over thinking and analyzing things. Hamlet is well aware of this flaw; he spends a whole soliloquy lamenting about it. In the end Hamlet can't change his own nature.
