What is the meaning of "unethical"?

The term "unethical" is defined as having no moral principles, meaning that an action or behavior does not align with accepted moral standards. The correct choice highlights this concept, indicating a complete absence of ethical considerations in actions. This absence can be contrasted with a state of having bad moral principles, which suggests that there might still be some kind of moral belief in place, albeit flawed. However, being truly "unethical" implies a disregard for any moral framework altogether. The other options suggest varying degrees of moral awareness or acceptance, but do not capture the essence of lacking fundamental moral principles, which is the crux of being termed "unethical."
