Ethical Theories-
Ethical theories are based on the previously explained ethical principles. They each emphasize different aspects of an ethical dilemma and lead to the most ethically correct resolution according to the guidelines within the ethical theory itself.

Deontology
The deontological theory states that people should adhere to their obligations and duties when analyzing an ethical dilemma. This means that a person will follow his or her obligations to another individual or society because upholding one's duty is what is considered ethically correct (1,2). For instance, a deontologist will always keep his promises to a friend and will follow the law. A person who follows this theory will produce very consistent decisions since they will be based on the individual's set duties.
Deontology provides a basis for special duties and obligations to specific people, such as those within one's family. For example, an older brother may have an obligation to protect his little sister when they cross a busy road together. This theory also praises those deontologists who exceed their duties and obligations, which is called "supererogation" (1). For example, if a person hijacked a train full of students and stated that one person would have to die in order for the rest to live, the person who volunteers to die is exceeding his or her duty to the other students and performs an act of supererogation.
Although deontology contains many positive attributes, it also contains its fair number of flaws. One weakness of this theory is that there is no rationale or logical basis for deciding an individual's duties. For instance, businessman may decide that it is his duty to always be on time to meetings. Although this appears to be a noble duty we do not know why the person chose to make this his duty. Perhaps the reason
