<blockquote>Your ethics change as your situation changes.
otherwise how are so many people corupted by power?</blockquote>
Is that necessarily a change in morality or just a lack of adherence to it?
Personally, I think that the basis for morality is instilled in us early on, then shaped by further conditioning, experiences, thought, education and intellectual development. That we learn the fundamental notion of what is good then refine it and tinker with it according to our learning and experiences, gradually developing a more accurate picture of morality.
Kohlberg's theory of moral development kind of confirms this.
Castro WTF?
