Evolution allows for no binding imperatives. Things happen.
There are no "goals" (for life to exist, improve, cooperate, be sustained, or continue.)
Life happens, but so does death. Cooperation happens but so does violence. If empathy happens so does jumping, swimming, climbing, burrowing in the ground.
Offspring are born, but not always. Mates are found, but not always. Life is not an imperative. Health is not an imperative.
In Evolution no "is" or "are" is an "ought" or a "must". In Evolution no "does, do, did, has" is an "ought" or a "must". Examples. 1. Termites are cooperative. But this does not mean that "ought" to cooperate or "must" cooperate. Bears do not cooperate. 2. Humans "do" show empathy. Insects do not show empathy, animals only operate on instinct. No animal says that humans "ought" or "must" show empathy.
The feelings of shame, remorse, empathy, cooperation are all traits that are never required responses, just like "jumping" is not a required response. Some animals jump, some don't. Humans may have remorse, humans may not. Evolution does not care if life exists, improves, thrives, survives, or ends. There is no goal, intentionality, purpose in evolution. Death is fine, shame is fine, selfishness if fine.
Atheists say, "But cooperation, morality, empathy improves and extends life." Improvement and comfort are subjective. A pig fines comfort in mud, should humans wallow in mud? Bears hibernate, should humans hibernate? Sharks can live 300-500 years without reading, writing, waring clothes, or leaving the ocean; should humans imitate sharks to extend their life? Atheists tell me "you ought to read more." I tell them to tell that to a Shark. A shark will ignore them as 1.7 million species will, and thus so will I ignore their commands. 1.7 million species don't read and in evolution that is okay, so I won't read either. They say we came from animals, but then ditch the entire framework that animals operate under.
