This is a book written so people could get to know more about who Cain was, as most only know him as the man who killed his brother Abel. The book engages in a plausible forensic study of Cain’s character and explores his humanity. This study is not dogmatic but provides probability to help determine who he may have been and how his life has impacted many. The writers used Scriptures to aid in mapping a possible psyche which led to the following questions: Was there a sibling rivalry? Was there possible animosity or jealousy? What was his childhood like, and how did he relate to his other siblings? Most importantly, what kind of relationship did he have with his twin brother, Abel? This book is not written as a rewrite of biblical Scripture or to create sympathy for Cain but written to explore his conceivable personality. Here is the case for Cain. You be the judge.
