I read The Great Cholesterol Con by Dr Malcolm Kendrick. On the basis of that I would never take statins.
If you look at a graph of deaths in women from all causes against their cholesterol level, the lowest mortality rate occurs at a cholesterol level of about 7.5. I think for men the figure is slightly lower, but not by very much.
Add to this the fact that the brain has massive amounts of cholesterol in it, and that cholesterol is vital for lots of different purposes in the body, why would anyone want to lower it?
And another point - high cholesterol in people is often a sure sign they have a thyroid problem, and in fact many years ago a high cholesterol level was used by doctors as a reason to investigate thyroid function. The medical profession should treat the underlying problem - the malfunctioning thyroid. Then the symptom - the high cholesterol - will improve by itself. (That is assuming you consider high cholesterol to be a problem - which I don't.)
