I often watch cock fighting when I was young because my father used to work in a cock fight arena. It was heartbreaking to see animals dying for the happiness of humans but everything seems normal to the viewers since it's a traditional game.
I'm not into games where animals are involved because for me, they also deserve to live and they don't have to sacrifice their lives for our selfish desires but we can't stop these gambling games because they are already part of our culture.
