Final answer:
Hamlet finds the speed of his mother's remarriage to be even more insulting than his father's death itself, exacerbating his feelings of betrayal and complicating his emotional state.
Step-by-step explanation:
Hamlet is very depressed about his father's death and thinks the speed of his mother's remarriage is even more insulting. This rapid remarriage to his uncle Claudius heightens Hamlet's feelings of betrayal and grief, making his mother's actions appear insensitive and reflective of disloyalty to his late father's memory.
T.S. Eliot discussed the complexity of Hamlet's emotions towards his mother in Hamlet and His Problems, indicating that Hamlet’s disgust towards his mother is excessive and beyond the facts, as her character does not fully capture the extremity of his feeling.
This excess of emotion becomes a core issue for Hamlet, complicating his actions and his perception of his mother's guilt, which Eliot believes to be an 'almost intolerable motive for drama'.
