And YOU do some research on Cholesterol NOT being the culprit for heart disease. What came first instilling the cholesterol fear or the drug.
Actually it all started from the observation that those with familial (genetic) high cholesterol had very high rates of heart attacks including in children. There is really no doubt high cholesterol is associated with high risk of heart attacks and strokes. This observation then led to studies in the wider population.
Since cholesterol is made by the body diet has little effect on high cholesterol levels. Diet and exercise are obviously good, and can reduce risk of heart disease and stroke.
Statins are natural products extracted from fungi like penicillin was. There is a nice history of cholesterol and the discovery of statins here.

An understanding of the history will make it clear that the problem of high cholesterol levels was recognised first then treatments were sought.
It is a completely different question as to the risk benefit ratio of taking statins, or any other preventative treatment. But it is clear from the history, drug companies did not create cholesterol as a risk factor. Cholesterol was recognised as a risk factor first then treatment was sought.
