There's a continuum of behavior which at the extreme absence of empathy we call psychopathy or sociopathy. But that doesn't mean more empathy is better. Sometimes it's good to be hard hearted. Should we have been nicer to the Neanderthals?

>>We'll never know. But we do know we evolved to cope with a world that is very far removed from the one we have. Is there any reason to believe evolution got everything right? We've already made changes to other aspects of our being, both physically and psychologically. But certain aspects of our behaviour still seem to be stuck in a distant past when life was almost always nasty, brutish and short.

Evolution sometimes saddles life forms with burdensome defects -- for example almost all animals can synthesize their own vitamin C; we lost this;

Which may have been an advantage where it was easily found in food.

Human's also have ridiculously thin walled arteries -- compared to most other animal species.

What's your reference for that? I've heard that pulmonary arteries have on average thinner walls - but you don't get strokes in your lungs.

In fact strokes are very rare in most species because their circulatory systems are superior in this regard to ours.

So why do humans live so much longer than other mammals, even much larger 

Evolution is a mixed bag and we got what we got -- both good and bad; the evolutionary benefits of an opposable thumb, enlarged forebrain, linguistic abilities etc. far outweighed the defects our evolutionary roulette wheel spit out and we have succeeded in covering this planet with members of our species.

Yeah, evolution doesn't aim for perfection, just 'good enough'.
