I really doubt Soros had a virus released that kills old people. He is old.
Soros is evil for the violence and socialism that he has promoted. But everything that is bad that happens is not Soros fault.
Viral research might actually be something good that he is doing. If however the lab didn’t have sufficient controls and there was an accidental escape of he virus, then you have to question was Soros’s investment somehow an enabler of those lack of controls.
Soros has never done anything good. The only good thing Soros could do is die.
