A smart(er) fella. Put him to him to work on an online medical degree so that he can be a prison doc/nurse for the rest of his life. The fear of the chair will make him useful. Make his family pay for his medical education + incarceration. He may be made useful alive.
As a prison nurse/doc he can use his conjugal visits to spread his sperm amongst several women who want brainy kids. His family can provide for them. Just need to prove the psycho gene doesn’t run in the family.
