Sometimes people just get caught up in something that doesn't necessarily make a whole lot of sense.
Even to them.
I often wonder at the motives that make people jerk like puppets on the end of someone else's strings. The motives that make them do things they wouldn't ordinarily do if they were thinking clearly. If they could see the "big" picture, they might not.
Sometimes our own egos seem to get in the way of how we were bought up, not merely educated.
I guess someone had to teach Nero how to play the violin.
