Look, I 100% understand that it's hard for good people to grasp that there are bad people in this world, evil even.
But speaking as a child who was abused for years, who showed very obvious symptoms of abuse and who watched as the adults around me turned a blind eye to that abuse simply because they could not face the fact that someone they knew, spoke with, worked with, were friends with could be so evil.
It's just not helpful to have that viewpoint. There is more to being "a good person" then just pretending evil doesn't exist, you cannot turn a blind eye because you do not want to face the reality of it. By doing so you are leaving victims to the wolves.
So far I believe Lucy is guilty, I believe the expert's, I believe the parents, I believe the Dr's. and ultimately I cannot get away from the numbers. I said it before, she's either the worlds unluckiest woman or she did this.
