A more thorough explanation:

Definition: Unethical (adjective) means not following moral norms or professional standards of conduct. Legal ethics (noun) refers to the minimum standards of appropriate behavior within the legal profession, including the duties that lawyers owe to each other, their clients, and the courts. It can also refer to the study or observance of those duties, as well as the written regulations governing them.

Examples: An example of unethical behavior would be a lawyer who lies to their client or the court. Another example would be a lawyer who takes advantage of their client's trust to benefit themselves financially. These actions violate the standards of legal ethics and can result in disciplinary action or even disbarment.

Explanation: The examples illustrate how unethical behavior goes against the moral and professional standards expected of lawyers. Lying to a client or the court undermines the integrity of the legal system and can harm innocent people. Taking advantage of a client's trust is a breach of the lawyer's duty to act in their client's best interests. These actions are not only unethical but can also be illegal and have serious consequences for the lawyer involved.
