Answer: Rationalization
Explanation:
Rationalization is known to be a process through which an individual show or prove an unacceptable behavior to be right or reasonable. It is a form of defense in which an act is been carried out for good cause or none. Furthermore, it occurs when an individual or a person give excuses for actions which can result in great and irreparable damages. Thus, rationalization is an unintended behavior.
