I'm not disputing the actual toxicity, I'm explaining how easy it would have been for Erin to assume it wasn't as toxic as many people think it is.
If you ChatGPT it now, it clearly states 10-30% reducing to less than 10% with the right treatment, it doesn't give another figure. Erin could very well have been working on this assumption.This doesn't in any way absolve her BTW.
We can't fully discount anything of course because if guilty we'll likely never know her motive, but I just don't find the idea that she thought she could murder 4/5 people and get on with her life very convincing. It would have to be an act of monumental self-sabotage or that of an unthinking murderer. It also raises the further questions of why those 4 particular people, and why she was so careless in hiding evidence.
When I look at the evidence and the definite facts we have, I see a woman who saw lying about having cancer as something that would benefit her. She looked for sympathy and got a kick out of people feeling sorry for her to the point where she faked it. If she was part of a great tragedy, then it would bring them closer together, and she could look like a saint for running around after the survivors despite having cancer.
