I want to put some light on those numbers [mortality rates] of corona positive elderly patients
Then please do so.
As part of a wider argurment, regarding the true number of deaths from Covid-19, I believe what you're trying to do, but with a lot of unnecessary padding, is to suggest that many elderly people who died during the epidemic, may or may not have been infected, but died not as a direct result of the virus, but as a result of being abandoned and left to starve or die of thirst.
(But this did not happen in the UK and your posts are couched in such a way to suggest that it did. This is entirely intentional on your part and downright silly. Your arguments would be more effective if you cut out the smoke and mirrors and came straight to the point. )
So now, having established that, let's discuss it.
Yes, some old people died in care homes in certain countries, of which the UK was not one, as a result of being abandoned by the staff. Those people may have been infected and most probably were. They are likely to have died anyway as a result of the virus but sadly they died of starvation and dehydration.
Many people of all ages who were infected with Covid-19 had compromised immune systems due to underlying health conditions. This is a very murky area because each case would have to be looked at on an individual basis. Let's take two examples,
a) Patient has circulatory disease and it is under control. Prognosis is that the person may live for another ten years or so, in reasonable health. They catch the virus, have massive blood clotting (which is apparently a common occurence in Covid-19 patients), and die of a stroke two weeks after diagnosis. Should this death be counted as a death from Covid-19?
b) Patient has advanced lung disease. Prognosis is a year at best. They catch the virus and are dead within a week? Did they die of Covid-19?
The issue is the way in which deaths are being counted. And there appears to be no consensus on how that's being done, nor realistically can one expect that there will be one. The most one could hope for, is that at least in the EU or in the USA, where there is a certain amount of connection between health authorities and certain basic standards, that there might be some agreement on how to count deaths. Even that is not going to happen.
I'll tell you now, exactly what will happen.
For the next ten years, universities and institutions all over the developed world will get hundreds of millions in funding, to rake through all the data collected, extrapolate and come to some kind of final figures on who actually died OF Covid-19 or WITH Covid-19 and it will remain a source of disagreement and controversy for another hundred years. In the same way that Holocaust numbers are still disputed, Covid-19 deaths will also be argued for decades to come. There is no definitive answer to the question at this time and there is never likely to be.
And here endeth the Lesson - go now, to love and serve the Lord ;)
