Bad Bloods are most often described as Yautja who choose not to obey the honor code and kill whatever they want, whenever they want, however they want. They enjoy the killing all by itself rather than enjoy the hunt that leads up to the kill. For example, say a pred comes accross a human baby. A respectable warrior would leave it alone. A bad blood, on the other hand, might leave it alone, or might kill it right there. For this reason, they are seen as outcasts. The Predatorrs don't want their technology being used for purposes they don't approve of. Because Bad Bloods need this technology to kill prey easily, they do just that. Of course, this is where the Predator law enforcement officials come in. By thee way, Bad Bloods and Solo Hunters are not the same thing. A Solo Hunter obeys the honor code, but hunts alone. Hope I cleared that up.
