Here's a verse for you from 1 John 3:12 "Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous."

If you have the time, here is an excellent video on the subject. Needless to say, I don't think that "fruit" from the "Tree of Knowledge of Good and Evil" was actually fruit but the act of sex with the Fallen Angels (another account is Genesis 6).

Cain is never mentioned in the lineage of Adam and it is not beyond the realm of possibility that Cain was NOT Adam's son but a son of the Fallen ones. You could argue then that it was out of jealousy of Able's uncorrupted blood that he killed him because God favored mankind's bloodline over that of the angels'.

I believe, also, that by the time Jesus Christ came to earth, He was on a "DNA rescue mission". If you believe in Him, God's Word promises that you WILL become a "new creature" (2 Corinthians 5:17). So what are you if you DON'T believe? Just my thoughts. Here is that video.
