How perfectly egocentric of you.  Just being born into the homo-sapiens species makes you special, and therefore entitled to commit any act of cruelty upon the other beings which inhabit your surroundings.  "Might makes right."  Perhaps you are an atheist, although the atheist side of my family was much kinder and compassionate than that.  The highest interpretation of a spiritual life is self-sacrifice, not exploitation.   It makes for some difficult choices in this world, but causing the suffering and death of other living, feeling beings in order to stroke one's own ego, get some prizes and bragging rights with one's equally low-standard peers, is on the low end of the totem.
