Do I need to watch bb before bcs

I'm aware of the generic title but I think in my case it's different. I know pretty much every major plot point and death in bb without even watching it I know >!that Walter, mike, hector and Gus dies and know exactly how!<. So at this point what's the point of even watching if I know the ending?! Do the means justify the end? Anyways I'm already 2 seasons into bcs and also know a bit of spoilers but not much I'm considering watching bb, so should I?
