Horror is a subjective interpretation of things which admits a fatalistic and helpless stance. The 'achievement of utter clarity' does not necessarily lead to horrific feelings. Indeed, one imagines it would be a driving force in the realization of what must needs be done and how to do so.
This 'horror' you speak of is rather a self-serving pity, an admission of weakness. Whereas 'utter clarity' implies strength in knowledge, you seem to believe it is a sober acceptance of limitations.
