It is also not enough to simply believe that something is the correct duty to follow.Duties and obligations must be determined objectively and absolutely, not subjectively.Deontology (or Deontological Ethics) is the branch of ethics in which people define what is morally right or wrong by the actions themselves, rather than referring to the consequences of those actions, or the character of the person who performs them.
These arguments are what ethics professor Tom Doughtery calls "agent-based" arguments by the Deontologist and Consequentialist because they are set up for one person's actions: moral ethics for the deontologist may instead make one prevent anyone else from killing the third stranger, withholding snake venom, lying to your mother, or singing show tunes at the tops of their voices.
A common criticism of deontological moral systems is that they provide no clear way to resolve conflicts between moral duties.
Being moral is thus a matter of obeying the rules laid out by that religion.
Deontological moral systems typically stress the reasons why certain actions are performed.
A purely deontological moral system cannot include both a moral duty not to lie and one to keep others from harm.
In the situation involving Nazis and Jews, how is a person to choose between those two moral duties?
To make the correct moral choices, one must understand what those moral duties are and what correct rules exist to regulate those duties.
When the deontologist follows his or her duty, he or she is by definition behaving morally.
Failure to follow one's duty makes one immoral.
In a deontological system, duties, rules, and obligations are determined by an agreed-upon code of ethics, typically those defined within a formal religion.
