Wrong, Jesse was a dealer before and Combo was his boy, they knew that skinny Pete had been in Los Lunas where he met Tuco, they had to know the risk involved, because they all wanted to stack benjies until the rubber band broke. Jesse stepped up to the plate and said he would handle the street side of the business, if he couldn't do that, he should have stepped off. Krazy 8 was hitter, he had his own area that he ran without Tuco coming in so i am sure he knew Krazy 8 and his cousin had put the murder game down before. Is Walt greedy yes but so was Gus, he was in the business for over 20 years and ran places all over the west coast, he had goons on deck who killed and expanded his areas also. Gus could have quit the business and ran his chicken places, he had 18 of them so he was making good legit money also. He was just as greedy as the next man.
