Great article; I remember reading 'The Lucifer Effect' by Dr Phillip Zimbardo and having this profound realisation about the idea of 'good' and 'evil'.
There is a small few who are inherently evil, but the most rampant and dangerous evil that happens is under the guise of good... and it seems that the only true moral action or way to tell whether we are good, is what we do when we recognise we've done something bad or wrong... because messing up, making mistakes is a given... what we do with them isn't.
What's that ol' phrasing....
'The only thing necessary for the triumphant of evil is for good men [and women] to stand by and do nothing.
