excitements to his vengeance
Walton is referring to Victor's own acute sense that the spirit world that
guides him is vindictive (3.7.7) and
exonerates him from normal codes of worldly justice or, indeed,
responsibility for his acts as a member of society. Yet, the emphasis
here on "his vengeance" suggests that Walton's apprehension is crucially
different from Victor's own and serves to underscore the delusional,
paranoid mentality that is now Victor's habitual mode of thought.
