I think individualism has dramaitically improved the human condition & was likely the real heart of Christianity in the first place. An atheist individualist is probably a better member of society than most religious people have been for most of human history. Belief in "God" doesn't magically make people good. Many just imagine that their "God" has granted them every psychopathic indulgence that crosses their mind, like the Israeli soldiers raping Palestinians, because they are "the chosen people" who can do whatever they want. But the athiest tendency to mindlessly worship the state produces equally horrifying conditions. And quite often the state & religious authorities have been one & the same.
