Control. All socialists crave control. In this case, charging and convicting PG&E would bankrupt the utility, allowing the State to step in and take control. Then they could solve "climate change" by raising rates through the roof, and only allowing energy use for "responsible" industries and individuals, while denying it to all others.
Don't think for a moment this is not their end goal.
Absolutely. Every effort they make is always a deceptive con job towards full communism as the final goal. The frogs are about to boil.
