so, the interpretation is, that Cain offered an empty sacrifice, perhaps he saw his brother do something, and merely aped the motions, wondering if he'd get magic freebies?
i perceive the topic to be important, as to when humans on earth are willing to accept, condemnations of other humans on earth, because of God in heaven, "give an inch, give a mile", so such seems a potentially important point
would Cain have committed the Eternal Sin of envying Abel's spiritual gifts ? Jesus' response, to Pharisees, about the Eternal Sin vs. Holy Spirit seems to say, that the Pharisees could have mocked even Jesus' body, calling him ugly (say); but to witness Holy Spirit in action, on earth, and to deny that God in heaven sent those Communications, e.g. Words to the mind and out the mouth of Jesus, is to incur Eternal Wrath. Thereafter, God in heaven will ensure, the disbelievers' Punishment.
I.e. you do not stare, at Super-Intelligence in heaven, Communicating to earth (thru Prophets), and claim your half-furry apeness is superior, because it (in your end) is not.

You mean Cain and Abel, right?
I believe this explains why Cain's sacrifice was rejected...
Heb 11:4 By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh.
Heb 11:5 By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.
Heb 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
Abel's sacrifice was acceptable to God because he offered it in faith whereas Cain didn't.
