Should the smallpox virus be kept or destroyed?

[Bootes Void]

This is an interesting question to ask in light of the Covid Lab leak theory. Right now the Smallpox exists in a lab in Moscow and Atlanta. Should the smallpox be kept around to study? or be destroyed?

There was also a lab explosion in Russia back in September 2019 that was under the radar, so there is a very small but existent risk that it can leak outside the lab.
