According to the bible animals where made for destruction anyways (just like evil apostates):
2 peter 2:12 (2 peter should be taken as a "falsified book" but taken that aside it still is a "canonical book"):
i But these, like irrational animals, j creatures of instinct, born to be caught and destroyed, blasphe ming about matters of which they are ignorant, will also be destroyed in their destruction
We see here that it is absolutely normal to kill animals and farm them and kill them... long live the bible :D HOOORAHHHHH
On a side note I want to add this: if they were made for destruction why are the JW's tought that these animals would be nice to eachother in paradise? It is absolutely bullocks according to their own book of power
