Weird conception of monotheism.Do not omit the infamous role of the monotheistic religions which have elevated man above the animal kingdom, wrongly, and who have decreed that God (call it whatever you like) had created us in his image. Therefore, how can we be surprised that we allowed EVERYTHING towards nature and its creatures ...
a) the human is not and has never been raised above the animal
b) humans were not created in the image of the creator of life.
c) he was never allowed to do what he wanted with nature and his creatures, but the reverse. Hence the non-consumption of the flesh of other creatures precisely.
