The author of Passage B appears accepting of the idea that behavior may be biologically predetermined in line with the author of Passage A's premises, but he rejects the idea that blameworthiness could be removed from the legal argot - the policy the author of Passage A advocates for ( lines 24-25). The author of Passage B explicitly states that he has "considerable doubt that any amount of scientific evidence could remove [the urge to blame] from criminal justice processes" (lines 40-43), thus doubting the feasibility of the proposal in Passage A.
Let me know if this helps and if you have any other questions.
