LDL cholesterol is known as the "bad" artery clogging cholesterol….but can there be healthy levels?

In what way could LDL cholesterol be vital for the body??? Is it possible to rid the body entirely of LDL cholesterol?? Does it exist purely as another way to die to keep the "natural order" of things???

You body needs some LDL cholesterol but the lower the better. There is a good type of cholesterol call HDL cholesterol and the higher this is the better.
