As her legal guardian, he had every right to request that she undergo euthanasia, but no law was on his side, so he had to watching his wife suffer for a long time while he fought in court against his parents. Prolonging such levels of suffering would only lead to heartbreak, financial hardship and, ultimately, futility. Instead, euthanasia allows for a peaceful death in a medically supervised environment. The person who suffers will not suffer and will retain their dignity. The bereaved family or loved ones will not spend a fortune that would bring them nothing.
