Yes. Because I am an emotional being with a life that I value. What happens to my perceptual and emotional being upon the end of my life is unknowable. I possess empathy and a subsumed theory of mind. I can project my own emotions and desires onto those of other beings. I therefore assume that all emotional beings value their own life as I do my own. Out of my empathy for others and my desire that others will empathize with me, I can value the lives of other emotional beings on their behalf. Because it is impossible to know with any certainty what of my emotional being will survive end of life, I place a very high. Perhaps the highest value on my life and by extension the lives of others. To me it seems that spiritual belief precepts which undermine the singular uniqueness of this life experience through afterlife or reincarnation mythologies those can only undermine and lessen the value i.e. the sanctity of life.
