Abstract：Some individuals are accustomed to doing immoral things in real life. From the perspective of psychology， the reasons for the above can be generalized into moral disengagement， self-serving justifications， double-evaluation mechanism， memory fading， etc. Moral disengagement causes individual’s moral cognition and moral self-reflection out of action in restraining， judging and regulating the current immoral behaviors， and relieves individuals from psychological conflicts or pressures arising from perceiving violation of moral standards. self-serving justifications is divided into pre-violation justifications and post-violation justifications. This mainly refers to the moral disorder of an individual caused by moral self-discipline before the immoral behavior occurs and after the immoral behavior is not discovered. When an individual is unable to shirk or defend himself/herself from immoral behaviors， in order to continue unethical behavior and maintain a positive self-image， a double-evaluation mechanism is enabled to distract others’ attention to such immoral behaviors. Memory fading means that an individual actively forgets or lets immoral behavior automatically fade， giving up the memory which may evoke negative scenes of conduct and concrete details， and excluding the memory which may cause threat to behavioral clues and details of self-concept congruency.
