For every person that thinks about creating the HIV-like deadly pathogen, there will be millions more thinking about how to defend people against such pathogen, how to detect it faster before symptoms arise, how to put up barriers to creating them, and possibly even how to modify our bodies to be naturally resilient to all similar pathogens. Just like what you're doing here. I don't think we should mark knowledge or intelligence itself as the problem. If that's true then we should be making everyone dumber.
