The use of the organic label is to distance people from this imagery by constantly repeating the propaganda that everything is being done 'nicely'. However, actually showing any kind of killing, no matter how nice, destroys that propaganda. The key trick is to use the correct words to make sure people do not conflate what they are eating with anything negative, and the organic label is part of that.
When you go deeper and attempt to explain how the killing is better, you simply open the audience to the fact that there is still killing being done. This is the wrong approach for the target market. It's better to distance the brand from the actual realities as much as possible.
