I beleive jodi is a sadist who played the part of an insecure masochistic, pathetic sexual barbie , in order to gain control over the poor victim Travis who was in his sexual adolescence and thought he was being slick,
Having several girls, enjoying being young in a repressive religious environment.
Jodi is a pure psychopath who is very obviously turned on by what she did, and very very turned on by the aftermath, her torture of his family, the reach she was able to create inside their lives, that she left her stain on them, this is ambrosia for jodi.
Planning travis's murder, having a gun, a plan, a plan to watch and enjoy the horror and grief and the sexual satisfaction was the greatest most exciting event of Jodi's life, it was thrilling and worth it..
Jodi got more guns (or another gun, glock? ) right away...to go camping and feel the thrill of shooting a gun again.
In Jodis mind, she owns the Alexanders, they are all a part of her masterpiece, she wants to cut them and nick them every chance she can, she loves them, she loves their pain...in her mind they are forever enmeshed.
This is Jodie's true nature, her calling... She should never ever be released.
