I think I know why Ruth chose to take the murder charge for her 5 year old sister. Remember when they ate cake in the restaurant, she said: "Katie, I'm so sorry I made you do that." Then Katie answered her:"Do What?"
It's AT THAT MOMENT Ruth decided she would take the murder charge for Katie. She does't want Katie has any memories about that bad...bad...things, she want Katie has a happy life without any burden from past, even that means she has to sacrifice her life.
For many people that's a silly thing, but IT'S A SILLY THING ANY WOMAN WOULD DO FOR THEIR FAMILY!
