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.
