i don't actually believe in good and evil. to me, that's just abdicating responsibility for oneself and one's actions: "oh, it was an evil thing s/he did - the devil made her do it," etc., etc. suggests an external locus of control. people aren't good or evil, but they do do either appropriate or inappropriate things. and appropriate is on a sliding scale, obviously: from saying something hurtful, to Mugabe.
oh dear - i've woken up with thinky head on...
