Not OP, but it's going to be really hard to assign a hard value to that. There are plenty of obvious examples where they denied a life-saving treatment. But many of them would've died anyway.

Then there are cases where they deny preventative/early treatments. Some of these eventually led to more serious and fatal conditions, some did not. How do we count these?

Then there's quality of life denials. These don't directly lead to fatal conditions, but can affect morale and the like, thus allowing more serious conditions?

All of it would be compared to the unexplored alternatives (where treatment was authorized). This is inherently an unknown.

I'm not defending him by any means. It's just that his body count is, at best, a rough estimate.
