God is not necessary for justice. A reasonable mind can reach the conclusion that if this is the only life we have, then it becomes infinitely precious and that it is infinitely precious to others and must be respected.
Why should we value the lives of others?
If life is INFINITELY precious, then MY LIFE is certainly more precious than YOUR LIFE!!
I should then do ANYTHING to preserve the single thing of MOST VALUE to ME, which is MY life.
This thinking means that ANY MEANS is justified for the protection (and continuation) of the singular most preciious thing in the universe. MY life.
Mass murder of those who perhaps MIGHT be a threat to me is certainly justifiable under this formulation.
This is NOT the thinking of a true atheist. This is the thinking of someone who makes themself a god.
The true atheist considers himself an accident who deserves to die, since it’s going to happen eventually anyway, and since there’s no hope of improving anything, as it’s all doomed to die and rot in the vast course of aimless time, it’s probably better to minimize the suffering (his at least) by getting it over with as soon as possible.
If one has a “goal”, or believes that we are “progressing” toward some “better state”, one is not an atheist. One is thus a religious person.
The only question is what is one’s religious “target”?
Is it the singular worthy one, or the multitudinous unworthy ones?
