Treating animals with disdain and utter disregard of their fundamental right to live are the epitome of the irrationality of humans, because when an animal is killed against its wish, it is clearly a sign of the use of force against a weaker animal. This is evident in the resistance provided by animals while being attacked for killing, and this makes itself a serious case of unethical behaviour against humans. Treating other humans with the same disregard would not be ethical, because it is to have killed a rational animal. Fox & Ward (2008) in their research found that participants were willing to restrict their diet to vegetables. They also were willing to restrict their indulgence in animal eating because of the environmental damage that comes with it, and the increased demand of animal treatment by veterinarians. This indicates that humans when made realised about the suffering of animals are emotional enough to avoiding killing them to eat them. Thus, suffering when contemplated and internalised makes one realise the pain of other animals. However, it is clear and rational enough that realising the pain and suffering of inexpressive animals does not require a deep contemplative discussion. It is evident by their actions and resistance to the force of killing. Hence, it is just a question of will that the humans must internalise to contemplate restricting their eating habits to vegetable, because animals are similar in nature, although different in species.
