Why does Kierkegaards philosophy imply that there must be exception to the categorical imperative?

Kierkegaard believed that ethical principles are not universally applicable because they do not account for the individual's subjective experience and relationship with God. He argued that an individual's personal relationship with God may compel them to act against universal ethical norms, creating exceptions to the categorical imperative. This emphasis on subjective truth and faith led Kierkegaard to challenge the idea of universal ethical rules.
