In my opinion: Some people live in a bubble. They like that bubble, it's nice and safe and filled with things they know and are comfortable with. It's easy to stick your finger out of that bubble long enough to point at someone, then retreat it safely back into your own know-it-all bubble of safety. People who don't live in bubbles have a hard time being a blamer. In order to accept responsibility, feel the consequences of their own actions, they must break that bubble and step out. That's uncomfortable for someone used to living in their own la-la land. In order to not always place blame on others you have to FEEL. You can't feel from inside a bubble, since you're "protected". Some people find accepting fault and feeling real things scary. So they point fingers all around, hoping if they point far enough away, people won't look at THEM. It's sad. It's insecurity. It's not really living life to it's fullest. It's not really feeling compassion or consequence. It's, well, living in a bubble.
