he killed his brother
Cain killed his brother Abel because he was mad that god looked upon Abel's offering with favor. He became jealous.
Genesis 4:5-7: "God did not turn towards Cain and his offering," meaning that He didn't show the same favor towards Cain's offering which He had bestowed upon Abel's offering. According to tradition, this is because Abel took pains to offer the best, while Cain was cavalier and offered whatever came to hand.

Cain likely knew his offering was rejected through a combination of his own internal feelings and possibly a visible sign from God. The biblical account suggests that God looked with favor on Abel's offering but did not regard Cain's, which may have provoked feelings of anger and dejection in Cain. Additionally, the lack of divine approval or acceptance could have been communicated to him in a manner that was clear, leading to his understanding of rejection.
