It has happened here.
The root of this evil is a shallow, materialistic view of human life. If a person can't work and earn money, can't enjoy sex or varied food, can't even watch TV, looks funny or takes other peoples' time, there is no value to such a life.
The only real argument to defeat this is to understand that life comes from God, every life is precious to Him, and therefore worthy of our respect and protection.
And isn't this the essence of the conflict? Those that lead the death parade are either the godless liberal/atheist/Nazi/commies OR they may profess a belief in God while denying His power and being void of reverence for Him. In fact, the scriptures speak very plainly of such people and we see them everywhere, but where they are truly dangerous are in positions of power over others. In this case, it is especially true of doctors and judges and administrators in various capacities, not to mention of a man who is abusing his "privilege" as a husband and guardian, all who have a vested interest in seeing this woman dead.
"This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, Without natural affection, trucebreakers, false accusers, incontinent, fierce, despisers of those that are good, Traitors, heady, highminded, lovers of pleasures more than lovers of God; Having a form of godliness, but denying the power thereof: from such turn away. For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts, Ever learning, and never able to come to the knowledge of the truth. (2 Tim.3:1-7)
