I want to know the answer to the following question:
Who blamed John's family background for his cruel personality?
All the background I'm provided with is that "Kate Norgate, for example, argued that John's downfall had been due not to his failure in war or strategy, but due to his "almost superhuman wickedness", whilst James Ramsay blamed John's family background and his cruel personality for his downfall.". Is that enough to answer the question?
Answer: yes
