I don't think you can hold Olivia accountable anymore than you can hold a real schitzophenic that's not been given medication for their actions. When you're that far gone, you can't really help but behave according the reality dictated to you. If anything, I'm more upset that Hugh didn't push his wife to get actual medical help. This was the mid to late 80s at the earliest, so this wasn't a thing that should have been so easily ignored. You don't just go on vacation if you wake up holding a screw driver to your spouse's throat.
But, really, I think that's the point: This show is about deeeeeeeply flawed people. Olivia is psychic, and she had alarm bells going long before she lost control. But she wasn't talking about half the things she was experiencing. So she has culpability there before she lost control. And I'm...fine with that, because that's this show's real message: About a family that deals with crisis and death in the worst possible ways, and has to ovecome that somehow. I like that they all kinda grew up to be assholes in their own way, and had to come to terms and grow past their trauma.
