Love and trust, contrary to popular belief, are not mutually exclusive. The perfect example is the parents of a shithead teen. Also, while I agree that Anakin was turned because of his bond and the way that Palpatine manipulated him through it, to say that he didn’t love Padme is simply untrue. What makes us fear loss of a loved one if they aren’t a loved one? Fear of loss is innately connected to his love for Padme, which is the reason that jedi aren’t supposed to have attachments so as not to be influenced by their emotions. The issue with it is that he stepped into the emotionality and let the fears, angers, etc. that come alongside love to win him over. Furthermore, it is unclear that he ever really returns from the dark side. He saves his son, but in doing so breaks the same code that he broke in order to try to save Padme. It just so happens that his son was one of the good guys. My argument here is that he was still a dark-sider, or at least quasi-darksider and could have still learned to become a force ghost through that.
