even Satan doesn't cross that red line:
4 “Skin for skin!” Satan replied. “A man will give all he has for his own life. 5 But now stretch out your hand and strike his flesh and bones, and he will surely curse you to your face.” 6 The LORD said to Satan, “Very well, then, he is in your hands; but you must spare his life.” 7 So Satan went out from the presence of the LORD and afflicted Job with painful sores from the soles of his feet to the crown of his head.
