Homie, "set your family up for life" is a retarded plan if what you're doing lowers the life expectancy of your family. Why worry about how much money they'll have 15 years from now when they might all be murdered
today?
And
at "she knew what could happen". She's a middle-aged suburban soccer mom that was constantly told "don't be silly, this is completely safe".
Illegal? Yes. Dangerous? No. Why the hell would she assume people would come murder her family, as if that happens to all drug dealers. 99.99% of the time dealing drugs ain't gonna get your whole family murked.
So nah, I can't really blame her for wilding out after Gus died.
And she ignored her lawyer because she assumed Walt would die of cancer before shyt spun out of control. She said something like "this problem will sort itself out soon enough". It's not as if this "wait for the cancer to come back" is a new plan. The only difference is she actually told Walt about it.
