I think Crow enjoys ownership, particularly of people and their legacies.
I'm skeptical that anyone worries about Thomas evolving. Everything I need to know about him is in this quote from 30 years ago
"The liberals made my life miserable for 43 years," a former clerk remembered Thomas – who was 43 years old when confirmed – saying, according to The New York Times. "And I'm going to make their lives miserable for 43 years."
Guys like him never let go of a grudge.
