Isn’t it rather peculiar that the one of the moral aspects concerning the death of a living organism seems like it is based on the size of the living organism for many human beings?
To put this another way, it appears that our moral beliefs diminish as the size of the living creature decreases and increases as the creatures get larger.
For instance, when bees & various other harmless bugs enter in our general vicinity, we might end up killing them without even thinking if killing them was the right thing to do. However, if there’s a dog in our general vicinity, we would consider it morally wrong to kill.
So why do we differentiate this way when both are living objects? Do we kill them out of fear? Do we kill them as a product of our evolution which became a passive reaction? Or do we sub-consciously perform a cost-benefit analysis in our mind to determine that killing the bee would be easier and more effective that trying some other forms of resolution?
I don’t think there is a solid reason to justify why we end up killing small living creatures, but I do firmly believe that if we are mindful of this change in morality based on size, we can allow more creatures to live harmoniously along side us.
