Singapoorean people are very cruel. what do you think?

I found out that many singaporeans are eating turtles as their dinner and lunch dishes.. most popular eaten turtles are eared eared sliders, soft shelled turtles, and even snake head turtles.. i went to many markets in singapore, and was shocked to find that turtles that are sold for restaurant tables are mostly found in the town side of singapore, like chinatown.. when i got to a market near chinatown, i saw many juvenile or roughly big red eared sliders kept in cages..each cage containing at least 10 to 20 live red eared sliders. the space was seriously cramped. the soft shelled turtles are all stuffed into ann empty pail, all waiting to be sold or killed on the spot. what shocked me most was when i saw the man selling them just use a knife and a sharp metal equipment cutting open the shell of a red eared slider, and digging and slicing the flesh out of a live red eared slider, while it just screeched and groaned in pain... this was consequently done the same to other turtles, frogs and fishes that were sold there.. i just cannot bear to see these people doing things like this just to satisfy their eating needs.. there are so many things they could eat, but why must they purposely breed turtles and other creatures just to kill and eat them? the reason they give is that the population of these creatures are overly populated, so they have to reduce the number of these creatures.. but seriously, they are the ones that breed them out of greed! please give me your views, thanks.
