I don't understand. Now that I've begun the book, Luca Brasi is mentioned much more and feared much more. However, I don't understand why that is. They show no example of what he's done in the past. Why is it he is so much worse than any of the other hundreds of guys the Corleones have? What makes him so special? The author showed us he was feared, but gave no reasons for it. At least, not up to where I've read, and i've read 100 pages.
