Two Sides To Every Story
When all the fingers are pointing at one person, it's easy to assume blame. If everyone agrees that this person is the problem, it must be true. Right?
Possibly, but all those fingers are refusing to see the other perspective. Maybe someone's actions are clearly wrong, but what's more important than blame is finding out why it happened in the first place.
Did that person fear something? Did they feel undervalued? Are they hurt? Their motivation may not absolve them of guilt, but it may shed light on other problems that people are better at hiding. Don't just follow the pointed fingers, look the opposite direction too.
