What is the ethical danger of using agents in negotiation?

A number of authors have suggested that when we act as an agent for someone else-particularly when the goals for that agent are to get the best possible agreement-agents may be more willing to violate personal ethical standards.In essence,acting as an agent may release people from their own personal ethical standards and code and allow them to create their own standards of legitimacy-that it is appropriate to do whatever is necessary to maximize the results for the constituent.
