This kind of gambling is always fun because these animals fights in the circle of human, have you been involved in this kind of animal gambling or have you watched such game before.
As someone who has pets, I don't think it's
always fun or never been fun. There's the satisfying feeling when someone sees the struggle of the other animal and the fight itself but that's not on me.
It's the culture that makes us think that it's fun but if you try to analyze the situation, you'll eventually going to realize that it's no fun at all.
Well, that depends if you really think that it's fun.
As someone who has animals as pets, it's not really very enjoyable to watch an animal suffer just because someone has placed a bet on it. Way back when I was still a child, I also engaged in some sort of betting on spider fighting. It was fun way back when I'm still not knowledgeable enough that they have feelings and they deserve to live too. But now, I wouldn't really place a bet on something that involves cruelty because it just tolerates and even boosts the urge of those people who organize such because there are people engaging in it.
Seeing how the two gamecocks fight against each other because humans tell them to and put them in such situation wherein survival of the fittest is the only way to be alive and fighting will be their only way out is such a horrible idea. But then again, not everyone possess the same level of empathy that a person has. It varies to different extent and some do not even possess it at all. If it's your definition of fun, I won't really support you, but I won't impose my beliefs on you.
