Il giustiziere della notte

The novel explores moral ambiguity around taking justice into one's own hands. I wonder what prompted Brian Garfield to delve into this theme and how he approached the protagonist's mindset.

The story makes a strong case for retribution, but also raises questions about the consequences of vigilantism. How did others interpret the morality of his choices?

Since 'Death Wish' is also a media tie-in, I’m curious whether that affected how the story was structured or the character development, compared to other crime novels.
