Deontological ethics allow people to stay very consistent because they would perform an act in pratically the same way each time they satisfy their obligation. In addition, followers of deontological ethics often place their duties or priorities on family, friends, or other people they are very familiar with. If the person had a duty to the general public, the system "places a cap on duty's demands" and "avoids the overly demanding and alienating aspects of consequentialism" [2].
The system also provides a reason for followers to be "supererogatory" [2]. In ethics, "supererogatory......indicates an act that is good but not morally required to be done" [4]. An example is if a man hijacked a bus of students and said if one person dies, then he will let everyone free [3]. The teacher who believes in deontology would volunteer to die because he feels it's his obligation to protect the safety of his students, and many others would view his act as "superergatory" because he is exceeding his duty to protect his students [3]
