In cockfighting, the cocks will have to fight to death or to the extent that one cock is several injured to the extent that it can later even die and be killed after. Humans are wicked has been the reason this kind of game is still existing. As humans feel pain, the animals are also feeling pain. Such games needs to be banned by the government. There are other games that are existing.
There are people who derives pleasures seeing cock fighting each others and they see it's as fun. Even if they are having fun with it, there should be a sets of limitations while these fights are going on, even human do have control and go for a rest while fighting but I do not see that happening direct with cockfights which I think there should be section where they fight and rest a bit maybe continue again just to make them have free space and resting time to relief some pains. Of course it would be fine is that type of gambling is being scrapped out because I do not see anything attractive to this type of gambling.
