What does the term "unscrupulous" imply about a person's behavior?

The term "unscrupulous" describes a person who behaves in a way that lacks moral principles and is often characterized by dishonesty or unethical behavior. When someone is referred to as unscrupulous, it indicates a willingness to engage in dishonest practices without regard for what is right or fair, typically for personal gain. This term strongly conveys a sense of untrustworthiness and a disregard for the consequences of one's actions on others, thus supporting the interpretation that the behavior is indeed dishonest.

In this context, the options that depict ethical or principled behavior would not align with the meaning of "unscrupulous," as they suggest an adherence to moral standards, which contrasts with the lack of scruples implied in the correct answer.
