Humans, just like other organisms, can't help themselves.
More seriously, we are expressions of replicating organic matter, the vessels for this process to continue to unfold. Humans are a phase in a long progression of evolution by natural selection. One day, just like long ago, "we" will no longer be around. And that's OK.

Many individuals can help themselves, but on the whole the species cannot.
