To get hypercrisis on it, Cain in Hebrew literal means metalSmith and Abel means herdsman. An idea is they are symbols for the conflict between settled farmers and hunter-gatheres just as the Garden of Eden is a symbol of the dawn of civilization ffo. Ignorant naked ape animal like living.
So Cains whole style, never waste life, control instead of kill, is like the farmer. Planting seeds and controlling life for your benefit.
Metalsmith also ties to how in Multiversity he and Immortal Man had the Rock as the first weapon, while Anthro had fire as the symbol of creativity and human ingenuity the rock was shown as the very first time the human mind "smashed against the natural world and turned it into something from their mind" that is knapping stones into arrowheads or the first murdur weapon ala Cain was the precuroupr to every sword gun and nuke forged from earth's materials. Cain, the Weaponsmith. and the metahumans here are outright called living weapons.
