Another theme could be the struggle between good and evil within a family context. One sibling might represent good, with moral values and a sense of justice, while the other succumbs to darker impulses like greed or envy. This can lead to conflict and division within the family unit, much like in the biblical account where Cain's envy led him to commit a heinous act against Abel.
Jealousy is often a main theme. Just like in the original Cain and Abel story, in a modern version, jealousy can still drive one person to harm another, perhaps over things like career success or a romantic relationship.
The theme of sibling rivalry is also prominent. In a modern day Cain and Abel story, siblings might compete for their parents' attention, inheritance, or recognition in society. For example, two brothers in a business family could have a bitter feud over who will take over the family business, with one feeling envious and resentful of the other's perceived advantages.
