Why should you expect ~2 million years of evolution to bread that out of us? The ability to start and control fires for warmth and cooking purposes greatly increases the odds of survival for individuals and their offspring. If I may personify evolution as form of rhetoric: evolution doesn’t care if you limp along through a painful life, or if your genes guarantee a horrific death at the end of it. Evolution only cares about your ability to produce offspring that in turn reach maturity and produce offspring of their own, and so on. Resources are finite in this world, so sure, the fittest tend to outcompete less fit creatures, and the former will perpetuate its genes while the latter won’t. This is where the notion of “survival of the fittest comes from”. But it is a mistake to interpret that implication the other way around: that is, survival does not necessarily imply greater and greater fitness over time. Evolution isn’t about species becoming the best they could be, it’s only about being good enough.
