12 not [living] like (or: not just as) Cain. He was existing, and continued being, from out of the condition (or: situation; or: one; thing; = influence) causing misery and hard labor (the unprofitable attitude; the worthless mindset; the wicked intent; the toilsome situation; the sorry plight), and so he slaughtered (killed by cutting his jugular vein) his brother. And on what score (or: for what pleasure) did he slaughter him? Because his works (actions) were gushed with misery and hard labor (were wicked or evil; were toilsome; were unprofitable and worthless), but those of his brother [were] ones in accord with the Way pointed out (just ones; righteous ones; fair and equitable ones; rightwised ones).
