In hard, cold reality, a person rarely seeks divorce for the well-being of the children. What is distressing about this myth is not so much the fallacy of it as its blatant hypocrisy. If people were really concerned for the well-being of their children, I would think they would move heaven and earth to transcend their false dilemma and move in the direction of responsible parenthood. With the use of this myth as a justification for divorce, humankind exposes its capacity for calling good evil and evil good. Here an act of selfishness is painted or portrayed as a noble act of self-sacrifice for the good of the children.
