Betrayal

Betrayal is bad in and of itself, since it assumes such an action comes from a perceived friend. The difficulty is when you perceive that the betrayal is even somewhat unintentional. If people had any idea how much they affected others, perhaps they would be a little more careful, less selfish, and a little more willing to be understanding of others and their circumstances.

But we are all prone to be selfish – and self-preserving. It's easy to think about one's self, rather than about others; that requires a risk. And you can't please everyone, so who do you say no to? Who gets the downside? Who has to suck it up? Those are the really hard decisions, and sometimes one makes mistakes, and wishes they had gone the other way. Nothing to be done now, one can't look into the past and change it at will - one cannot change it at all.
