One would simply prolong the life of suffering and pain while spending a lot of money. There are thousands of cases where a family has gone bankrupt to ensure medical care for a terminally ill person or to keep up the treatment for an incurable disease. Prolonging such lives would only lead to heartache, financial challenges and eventual futility. Instead, euthanasia allows peaceful death in a medically monitored environment. The person suffering would not suffer. The family or loved ones to be bereaved will not spend a fortune which would yield them no returns.
