What is Hamlet's tragic flaw primarily centered on?

Hamlet's tragic flaw is primarily centered on indecision. Throughout the play, he grapples with the moral implications of avenging his father's murder and often delays taking action. This indecisiveness is evident in his soliloquies, where he contemplates the nature of life, death, and duty, and it ultimately leads to his downfall. Hamlet's inability to act decisively allows external circumstances, such as the machinations of Claudius and the reactions of other characters, to dictate the course of events. His internal struggle with fear, doubt, and existential thought creates a conflict that prevents him from fulfilling his vengeance until it is too late, culminating in tragedy not just for himself but for those around him. This characteristic flaw of indecision is a critical element of his character and drives the narrative's tragic progression.
