Do humans feel guilty for what they don't do? Yes; each and every force in this world affects humans silently and forms them as they choose in conscious and unconscious ways. When intelligence and education weren't introduced at a prehistoric age, people were evolving with finding the most common ways, and most people's common sense became the education of other people.

Humans are not uneducated but they ignore their common sense with more educational beliefs and confidence.

Common Sense, a slim book, is focused on how humans are missing the opportunity of common sense in their life and how they can implement it as a conscious part to make and remember it for life forever.
