Final answer:
The relativist perspective defines ethical behavior subjectively from the unique experiences of individuals and groups.
Step-by-step explanation:
The moral perspective that defines ethical behavior subjectively from the unique experiences of individuals and groups is the relativist perspective.
This perspective holds that ethical standards and behavior are not universally applicable, but rather vary from person to person and culture to culture.
For example, what is considered morally acceptable in one society may be regarded as morally wrong in another society.
