Yeah, No.

The world isn't just "Black & White". There is almost everything in Grey.
Also, it is very hard to really define and determine "a good cause".
For some people "a good cause" means to make a lot of money, for others it means to make people happy, or just to "express themselves".

I beg to differ, that you can not sort every human being into either "totally evil and malicious" or "totally good and pure" - because that is what "Black & White" entails.
Or else, people are both at the same time and nobody will have "a good cause" because all causes are equally just or "good" and judging them would be illogical.
