Each person's happiness is equally important. Mill believed that a free act is not an undetermined act. It is determined by the unconstrained choice of the person performing the act. Either external or internal forces compel an unfree act. Mill also determined that every situation depends on how you address the situation and that you are only responsible for your feelings and actions. You decide how you feel about what you think you saw.
Immanuel Kant (1724-1804) had an interesting ethical system. It is based on a belief that reason is the final authority for morality. Actions of any sort, he believed, must be undertaken from a sense of duty dictated by reason, and no action performed for expediency or solely in obedience to law or custom can be regarded as moral. A moral act is an act done for the "right" reasons. Kant would argue that to make a promise for the wrong reason is not moral - you might as well not make the promise. You must have a duty code inside of you or it will not come through in your actions otherwise . Our reasoning ability will always allow us to know what our duty is. Kant described two types of common commands given by reason: the hypothetical imperative, which dictates a given course of action to reach a specific end; and the categorical imperative, which dictates a course of action that must be followed because of its rightness and necessity. The categorical imperative is the basis of morality and was stated by Kant in these words: "Act as if the maxim of your action were to become through your will and general natural law." Therefore, before proceeding to act, you must decide what rule you would be following if you were to act, whether you are willing for that rule to be followed by everyone everywhere. If you are willing to universalize the act, it must be moral; if you are not, then the act is morally impermissible.
The differences in the Utilitarianism and the Kantian views are as different as night and day.
