Sorry. I have to give the Schindlers some slack. As a mom, I can't fault them for trying everything they could to save their daughter.....rational or not.
They don't strike me as insane. Felos does.
They tried AS DID her husband for years to escape the reality of the situation. There comes a time when the best is to let the loved one go home to her maker. THAT is the true test of love not some selfish clinging to a shell and sham.
Occasionally you hear of some poor soul who have the corpse of a loved one still at home in bed for months or years after the death. That is love too but madness.
