Did they seriously spoil the ending of breaking bad in the first sentence?
The last episodes of Breaking Bad have only been on Netflix for about 6 months. It's completely plausible that people who decided to start watching after the series reached its critically-acclaimed ending might still be a couple seasons shy of the ending. Hold your spoilers for another 3-6 months to be safe.
spoilers:
WW didn't die violently because of anything about the drug business. He was dying of cancer and chose to take risks that would have had him die violently no matter the outcome. The specific business he was in was immaterial.
In the end he died from his own bullet, but not until he'd asked his former partner to shoot him dead and been turned down.
