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.
If it’s grey, it’s percentage of black!
