In this case, you are thinking of ending the life of the human race. At a time when everything is progressing and leaping, you want the regression of mankind! At a time when even bacteria and viruses have become more mutated and are constantly making themselves stronger, as well as animals, the regression of mankind means its destruction, instead of destroying technology, it is better to teach the culture of its correct use. Let's teach humanity and goodness, as long as the superpowers of the world for their own interests and a few arms companies are constantly causing war and killing, teaching our children to be good will never succeed.
Never worry that you are eating a living being, because at the desired time (after death) you will also be eaten by the same living beings (by decomposing the organs in the soil and using the roots of plants and other animals from the organic matter of the human body for growth and continuing your life) and this is the cycle of life, so as long as you are alive and living, be happy and give happiness and goodness to others
