Well he didnt exactly kill them or stab them but he did starve some animals, used them as fighting dogs, putting 2 dogs that attack eachother in a cage is killing them basically, they just wait until 1 animal is dead, that is killing dogs. Dog fighters also use small animals like lost poodles and kittens to put in the cage with the dog so that the "dog" can practice on the small animals. I hope you get put in a cage with a lion and see if the person who put you in there commited murder or not.
