Please see these short videos (<20 minutes each) from Dr. Roger Schuelt from the UC Riverside Medical Center. They include the molecular biology of the virus, of glutathione, and how the virus and glutathione interact and counteract.
I know there's a lot here, but if you were serious in your ask, this should answer you.
This is the most medically heavy video, but sets the stage at the molecular biology level for the subsequent videos.
Coronavirus Pandemic Update 63: Is COVID-19 a Disease of the Endothelium (Blood Vessels and Clots)?
This video continues the discussion by focusing on the oxidative stress that results from lack of glutathione.
Coronavirus Pandemic Update 65: COVID-19 and Oxidative Stress (Prevention & Risk Factors)
This video focuses on NAC and Glutathione as a means to reduce oxidative stress.
Coronavirus Pandemic Update 69: "NAC" Supplementation and COVID-19 (N-Acetylcysteine)
Glutathione deficiency from oxidative stress is discussed.

My wife and I watched a lot of his videos.
The NAC issue is real and this is what could have helped these people with ARDS.
Specifically, GlyNAC, adding glycine to NAC, is best.
