I believe the focus on LDL as 'bad' has been misguided. It's an improvement from 'all cholesterol is bad', but we just don't understand very much about how it all works, and so as we discover more, we slowly refine our understanding.

A lot of the theory about why LDL is 'bad' is based on the fact that arterial damage is repaired with the stuff, causing plaque. There's no evidence that LDL is causing the damage, just that it has a role in how it's fixed (in an ultimately detrimental way).
