Environment and society determines to a large extent, our view of the world around us. Yet within the same environment, we have different perspective on life.
I think the most important thing is how people react to their environment, their situation and society.
The question then is, do those who become wolves do so because they didn't have it in them to react positively to their environment and vice versa?
In each moment, we are all doing the best we can with the tools we have availabl. This doesn't mean we can't sharpen or add new equipment to the toolbox.
