Lifetime’s euthanasia Drama, Mary Kills People, is no longer just championing the cause of assisted suicide for the terminally ill or those suffering from intense physical pain. Now, the show supports euthanasia for those enduring great emotional pain, such as due to the death of a loved one. ER nurse Mary Harris (Caroline Dhavernas) kills people so that they can die “with dignity.” Monday night’s second season premiere, “The Means,” had Mary justifying her decision to euthanize both a man dying from mesothelioma and his perfectly healthy wife because they want to die together.
