(VIDEO) Any Advice on Training my Dogs to Become Champion Fighters?

I've been trying to break into the glamorous world of illegal dog fighting. I've gotten Baloo and Ivan to the point where they'll fight (as you can see in the video posted below) but neither one of them seems to have the "killer instinct" of a true Vick-level champion. Any advice on how I can turn my dogs into remorseless canine murderers? (Note: I have my six year old in there training to become a dog-fighting referee but I wouldn't be above dressing her in a Clifford costume and using her as a bait dog if you think that might help)
