The words "deserved what he got" are Cain's thoughts, where he rationalizes the brutal murder of his brother as being Abel's own fault. In other words, Abel caused Cain to murder him, meaning Cain was not really guilty of his brothers murder.
(1921-2010) are the birth and death years of Thomas Molnar. He was born in 1921 and died in 2010.
Thank you very much!
I saw 1921, but was “seeing” 2021. Derp.
