Taking away a human's life is considered immoral, unethical, and unlawful, and it is considering a crime. In other word, I'm totally oppose the idea of euthanasia. Euthanasia is "Inducing the painless death of a person for reasons assumed to be merciful?". I don't think the individual, the family, or the government should have the right to end a human's life.

The Thanatron released an anesthetic and then a lethal injection of potassium chloride that goes through the veins. Potassium chloride is a chemical that causes the heart to stop beating. The government uses this same chemical for executions by lethal injection. Kevorkian started gaining popularity because of his new death machine. In 1989 a 54-year-old...
