It is very common in that part of the world for them to de-fang the snakes (and although it is wrong to do so to any degree, they are generally not de-fanged in a nice way, just ripped out). This one may be defanged too, i don't know, but this is an example of another common practice which is sewing the mouth shut. Basically the snake will have a long horrible death, while being constantly stressed by humans (as it is in the video). It is extremely, totally, sick.
