Why Having a Conclusion Oriented View to Action does not Necessitate the Negation of Its Ethical Title?

The present writing researches ethical finality. Some scholars believe this view necessitates the negation of the ethical title of the action and thus believe an act is ethical when it is merely done as a duty, regardless of its conclusion and goal. But I believe having a conclusion oriented view to the performance of an ethical action does not necessitate the negation of its ethical title and on the other hand, it is an encouragement and motivation for the performance of the ethical action. Not only these encouragements, according to the Islamic view, has no obligation, it is rather emphasized and recommended.
