Doctors seem to have no doubt. They made an oath. The definition of Euthanasia depends on whether it is active or passive. Active Euthanasia is only allowed in Holland, and it means that the doctor takes direct measures to put a patient to sleep, whereas passive Euthanasia only involves stopping pill consumption, or stopping treatment. In England, only passive Euthanasia is allowed.
Euthanasia touches some of the deepest feelings in human beings.
It is the power over life and death, and responsibilities no one wishes to take, have to be taken. This, of cause, leads to the ultimatum, that it is the patients own choice. From the patients point of view, a lot of arguments talk in favor of euthanasia. For one, no body wants to be a burden. It can also be mentioned that the life quality of a terminally ill patient, gets reduced a lot.
