Molly's choice

In The Finite Canvas, Molly decides to turn Jada into the authorities, ultimately killing her. She's been alone for quite a while when she meets Jada and even comes to "love" her. Molly indirectly kills Jada because she says she "thinks she wanted me to kill her". At the same time, she is persistent in asking about the fifteen thousand dollar reward. Do you think Jada wanted to be killed? Would Molly carve a design into herself if she killed just for the money? Did she just want the money to cure her breast cancer? Did this story remind you at all of The Man (the killing of a friend for their 'benefit')?
