Yes because despite the known risks we need to understand these viruses and what causes across species transmission so that we can prepare for future pandemics (even those caused by spillover mistakes) and what we learn may also prove useful in other applications. Otherwise we are in the dark with unknown unknowns which is not a good place. So the risk here of doing research is manageable.
