Final answer:
John Stuart Mill, a utilitarian philosopher, would likely judge the morality of euthanasia based on its consequences and the overall happiness it brings.
Step-by-step explanation:
John Stuart Mill, a utilitarian philosopher, would likely judge the morality of euthanasia by considering the overall happiness and well-being that it brings. Utilitarianism holds that an action is moral if it produces the greatest good for the greatest number of people.
In the case of euthanasia, Mill would assess the consequences of allowing or prohibiting it and weigh the amount of happiness or suffering that would result.
If euthanasia is shown to reduce suffering and improve the quality of life for those who choose it, Mill would likely support it as a morally permissible option.
