Again, I never claimed that there has been zero corruption, that is your strawman. What requires evidence is that corruption is the reason for large numbers of reported covid deaths, in the face of the obvious alternative explanation, which is that it's substantially more contagious and more deadly than the flu.
If I started from the assumption that if someone has a motive to do something nefarious then they probably did it, and then had to work to disprove it, that would be corrosive to all human relations. How could you even function in society under that worldview?
