ah yes ive seen that picture from 96 of senter. i emailed walter mack a few months ago to say hello and asked him whether he thought the likes of borelli would look back and have some remorse for what he did. his response... "i doubt it". having read murder machine the book portrays borelli as being a clinical professional but with a bit of a heart - referencing the conversation he had with dom when he thought dom was sent to kill him. in the end i'd imagine he is just as much a sociopathic maniac as senter and testa.
