The nature of rebellious man unfolds in the person of Cain who had an auspicious beginning as the child of hope. But the narrative lines him up with the curse; he worked the soil. Abel, however, seems to be lined up with man's original purpose, to have dominion over life (cf. 1:28); he kept flocks. These coincidental descriptions are enhanced with their actions in worship. Abel went out of his way to please God (which meant he had faith in God, Heb. 11:6), whereas Cain was simply discharging a duty. Abel's actions were righteous, whereas Cain's were evil (1 John 3:12). These two types of people are still present.
