OTWO, adultery is treason it destroys families, it takes a terrible toll on children it is a sin, it cuts a-sunder , creates a "sound" like in "Puget sound" , a separation.
Now in evolution, adultery might produce a Kenian sowing his wild oats abroad and the target family nurture a presiding overseer. A adulterous mother might raise both a sprinter and a marathon champion, as half brothers. but if you want family, society peace and a safer pace. believe me,
adultery is a sin. a breach of contract with all parties involved.
