Should princes be concerned with behaving ethically or practically

Machiavelli produced a practical guide to the arts of statecraft, which served the practical needs of the powerful families that emerged in the Italian  city-states during the Renaissance. Statecraft involved carefully crafted approaches to the realistic conditions faced by rulers. It was driven less by emotion or morality but reason.
