We all have to choose our particular values in life, NoMercy.
One of mine is unquestioning loyalty to my friends ... even when I disapprove of what they have done, or disagree with them.
It's not a perfect philosophy, but everyone knows where they stand with me. I'm black and white loyal.
The moral grey area is something that I leave others to struggle with.
I'm not the moral guardian of the whole world, but it would have to be something REALLY serious before I betrayed a friend or loved one ... REALLY big !!
