The final straw for me was during a CO's talk. He was relating an experience from a shepherding call. The brother he was visiting was strugging spiritually due to multiple personal problems he was enduring. He told the CO that he couldn't wait for the new system to get here so he didn't have to deal with all of the problems he was facing. The CO's response: "What makes you think you'll be in the new system?"
I shouldn't have been stunned by the utter lack of empathy, but somehow I was. That was it for me.
