I am with you on hills and valleys - just don't like the 'valley of despair idea (which you didn't mean, I know).

And I agree - nothing justifies their actions. They have a compassion and empathy bypass, and what they do is cruel. This has nothing to do with 'your point of view'. If they argue it is their choice to act as they wish, then we also have choices, and mine is to not have that person in my life.
