"Evil
occurs when individuals or groups embrace codes of conduct or
standards
of behavior for their own personal well being and social approval,
yet
violate those very same codes or standards to undermine the personal
well-being
and social approval of others.
"Corruption
occurs when individuals or groups for their own benfit, violate
codes
of conduct or standards of behavior that they profess, or are expected
to
uphold."
