Hm, how to clarify. Anakin Skywalker had issues, its just that the Clone Wars (and Palpatine) really messed him up. By the end, he wanted to be powerful enough to "protect" his wife from anything, and controlling everything, for the sake of order. Cade on the other hand doesn't have that kind of obsession. As a pirate and even later on with Krayt pressuring him, he's just not interested in the "join the darkside and rule the galaxy!" sales pitch. Which is one of Cade's good points. Its not a problem right now, just by later on, when there's plenty of other characters fighting against the Sith and we're still stuck with long arcs with Cade, while the rest barely get oneshot issues here and there. Cade's issues were believable and sympathetic, just unfortunately for him, as Luke said, his destiny will come find him, no matter what, which kind of leans towards making the Force really annoying. Things usually work out, with an all-guiding energy field, but that doesn't make the losses along the way hurt any less.
