A thought recently came to me and I realized, Starkilling entering the cave of evil on dagobah, is really not the best idea.
We already know he struggles with the dark side and in Episode 5, Yoda clearly explains that the dark side is strong on the planet and especially in the cave. It should of caused him to go darker or at least have some profound effect on him.
Not to mention there is no struggle with the dark or light side in TFU2. And if he is trying to be a jedi, his attachment to Juno will only cause him to fall or at least, not allow him to be a true jedi.
"I've got a bad feeling about this!"
