Utilitarianism can lead to social injustices, particularly in social distributions. In the process of promoting efficiency, productivity and convenience, utilitarianism fails to account for basic principles that in justice cannot be modified. Deontological theories state that moral standards exist independent of the end results. Rather, ethics come from a binding obligation or duty to do right. Actions are morally wrong not because of the consequences, but because the action itself involves a moral violation.
Philosophers promoting deontological thinking further suggest that motives matter.
That is, some motives are more morally pure than others. The idea of motives behind an action also plays into the determination of whether a given act is or is not moral. Essentially, the thinking here is that any person can act morally, but there is more to a moral evaluation than simply what was done. We must consider why the action was done. Theory Rawls s Theory Emmanuel Kant suggested that an act is morally praiseworthy only if it is done from duty, not from self-interest or natural inclination.
