You have yet to show that tripling denials of a particular category of claims is even wrong in the first place. Let me repeat: any system will deny some claims, so denied claims are not prima facie evidence of anything wrong.

Decision was made to actively increase unnecessary deaths for monetary gain

Nobody had shown any evidence whatsoever that anything like that happened. Not only are denied claims not automatically wrong, but also changes in denial rate do not even need to correspond to any decision or change in policy, but may instead result from changes of external factors.

He ultimately approved of that decision

What decision? You just assume that there had been some decision, that Bryan Thompson approved, and that it was nefarious. There is as of now zero evidence for this, this is just your speculation. Murdering people based on speculations like that is profoundly evil, and so is excusing it.
