This seems like a misunderstanding of how evolution works. Viruses don't choose to be deadly or not based on some evolutionary path that they see ahead, the causation goes the other way around - viruses that were deadly in the past might not have an evolutionary path to the present. We do not know how Sars-Cov-2 will end up - we cannot pre-emptively discount the potential of deaths just because it seems like a bad evolutionary strategy.
