Anyway, they beat dogs not because they like to see dogs suffering but because they don't think it's wrong. Asian people are not cruel people. The are tender-hearted, compared with westeners.
Anybody who could do what you describe is far from being "tender-hearted". One does not need to be indoctrinated by "religion" to understand basic concepts of right and wrong. To cause a living creature such horrible anguish is obscene. But, to inflict such agony on a creature that befriends man, who understands human commands, and who lavishes man with love and affection, is uncomprehensibly sinister. This ruthless act of cruelty could not come from a person with a "tender-heart", but from one whose blood runs cold through his veins like a lizard.
I'm sure MANY former POWs would also have a word to say about the "tenderness" of their Asian captors hearts.
One thing you have to understand is they don't treat animals like human beings. Also they don't develop affection towards dogs as westeners do. So in their eyes, dogs, cats, pigs, cows, chicken, fish... are the same aniamls. Another reason for them to do so may be because they don't have the tools or know the methods to deliver a quick kill. They have to resort to the primitive ways, like how people were executed in ancient times.

As for POWs, there was politics involved.
