Copy cat!
Ahem, but to answer the question, I feel that this is like the alcohol situation, but worse. Not only do I disagree with the theory for all the reasons I disagree with the intoxication defense, this one doesn't even require a person to ingest a mind-altering agent. It means the risk that they will commit a crime is inborn. That means it's hard to avoid, harder to change, higher of a risk.
