Removed the following from the entry on the Bibe: "Abel gave the best he had in an earnest desire to please God. Cain just gave whatever was lying around, in order not to be shown up by his younger brother. More to the point, "Without shedding of blood, there is no forgiveness of sin." Cain was mad because Abel doing it right showed Cain wasn't paying attention. Not to mention God cursed the soil earlier on. Cain giving God something born out of something that He cursed isn't exactly a good way to please God. As You Know, Cain kills Abel."

This sounds more like a Draco In Leather Pants attempt to justify Cain.

Should this trope be renamed 'Cain and Abel Story', or would that be a seperate trope?
