Final answer:
Moral relativism is the ethical trap described in the question, which rejects the idea of moral absolutes and argues that morality is subjective and varies based on circumstances and cultural norms.
Step-by-step explanation:
The ethical trap described in the question is called moral relativism. This is the belief that there can never be a universally right or wrong response to an ethical dilemma because morality is determined by the circumstances or cultural norms. Moral relativism rejects the idea of moral absolutes and argues that moral judgments are subjective and vary from culture to culture. For example, what may be considered morally acceptable in one culture may be considered morally wrong in another culture.
