The devil s advocate view:
We humans are an intellectual and highly communicative species that uses emotion-laden words and body language to convey thoughts. It is fairly easy to understand, or at least see, the agony a fellow human being can be in because of the attributes we associate with it. With other animals, however, identifying suffering becomes much more complex.
Animals more closely related to our species, such as chimpanzees, demonstrate similar emotional and intellectual qualities that often lead humans to more readily apply moral and ethical reasoning in regards to their welfare.
Other animals, however, such as snakes or goldfish, may seem to be so distant from humans that it is hard to find the same concern for them (Mather, 2001). While our tests for emotion and intelligence may not reveal any substantial results for these types of animals, it is also fair to question if they are simply inadequate tests based on faulty human interpretation of non-translatable factors.
How can we then determine which animals suffer, to what degree they suffer, and whether or not humans should take these factors into consideration in the treatment of those animals?
While emotion is probably the most accessible indicator of an animal’s distress, not all animals were created to outwardly express those feelings (for example, perhaps because they lack comparable human facial muscles). We must also consider the dual definitions or interpretations of the word ‘feelings’; there is a qualitative difference between expressing a physiological reaction to something unpleasant (e.g., a reflex, a purely physical and instinctual response) and cognitively appraising the cause and implications of that pain (e.g., psychological suffering)"
So why are domesticated animals allowed for us to eat? Is that not suffering of these animals?
Can can we humanely do that?
Now the general question is why has GOD allowed all of us here in the earth to share this "bizarre " life of a mixture of good and evil?
In reality it just depends on the human . Bad humans leads to oppression and suffering. Good humans have more compassion for GOD s creatures.
However all humans consume meat and farmers/keepers of Al Anaam/live stock must survive.
So GOD does not interfere and break His promise of allowing humans their fife of "free choice" with responsibility on earth.
GOD is allowing both good and bad to exist . The humans are the ones making the decisions and the choices of what we see and live.
The animals have submitted ,declined the responsibility and accepted their roles . Their reward is awaiting them.
Do not worry,do something positive and helpful to all GOD s creatures,fight for justice and decency and GOD will judge fairly on behalf of all the creatures.
GOD bless you.
Peace.
