About 10 years ago, a 'friend' of mine in my hall was appointed an MS. He hated it, he wasn't interested in reaching out etc, but he didn't want to turn it down. He only lasted a few months they deleted him as an MS, he moved away didn't hear from him again.
In a KH about 10 miles away, a guy was appointed an MS, he was big friends with the PO at the time. It came out that he was abusing the children he gave a lift to on the way to the meetings. It had been going on for a number of years. He was appointed right in the middle of it.
I remember thinking there's no way the 'holy spirit' appoints people. It still took a few years for the wheels to fall off the wagon altogether.
