A Great article here by Revd Nemu using Stanley Milgrim's classic experiment to reflect on the meaning of evil and how it relates to our inclination to obey authority.
It is not the people in the multitude which are evil, nor the following, but the deed. The word ‘evil’ suggests serial killers and souls that are blacker than the inside of a wolf’s gullet, but ‘evil’ is more complex in Hebrew.
Nemu uses the game of chess as a metaphor of a game of chess to describe how power is and can be played out. This reminds me of something I read years ago in Lyotard's 'Post-modernism' (or whatever it was called!): "If there are no rules, there is no game".
And while you're browsing have a look at Revd Nemu's blog too.
