Animals not having reason is not a justification to torture and murder them. We do not kill and eat retards for that very reason. There are many human beings who are actually lower in intelligence than animals, but we do not eat them because a lack of reason and intellect is not a justification for murder.
We are supposed to protect the most vulnerable members of society, not abuse them.
