Causes

Euthanasia is caused by the pity and sorrow of someone experiencing great amounts of pain. Most people in North America endure at the end of their life what may be called a bad death, more often than not, patients died in pain. Some other causes are people who have a severe illness or would not be able to come out of a coma. Sometimes a physician will give the patient a lethal dose of sleeping pills, or could get instructed to commit suicide by using helium  or carbon monoxide gas to poison the suffering patient.

How people commit the crime of Euthanasia
They might remove life support equipment such as respirator removal or shut down, stopping medication needed to sustain life, not delivering CPR (Cardio-pulmonary resuscitation) and allowing the person to die. Possibly the most common form of Euthanasia is to give the patient high doses of morphine to control pain, and hastening death's grasp.
