Morality will consist in acting out of duty.
For example: killing. I have chosen utilitarianism as opposed to Virtue Ethics because I believe that euthanasia is trying to address how to make people with disabilities and those who are affected by it as well happier.
We should not make exception of ourselves. Euthanasia is natural in a way because in real life, there is a matter of life and death. But this is not bringing anyone happiness, certainly not those with disabilities and their friends and families as well.
The selfish ideas that it would be more beneficial for a disabled person to die, so that we do not have to see, hear, or talk to them, is unfortunately ingrained in American culture. In applying euthanasia to consequentialism, consequentialism has only one duty which is to maximize good consequences.
For example: if you want to be healthy, you have to eat healthy food.
