How could he tell Obi-Wan that fear of killing him and Padmé (of doing atrocious things while under the influence of the Dark Side) kept Anakin well back from that temptation, when fear, to a Jedi, was the first step down the path to the Dark Side?
“I know that. I don’t want to hurt you or Padmé- Ani, anyone else here.” He knew why Obi-Wan was asking these questions – Anakin had within him the potential to wreck tremendous havoc on this world. But Anakin still didn’t like them; though answer them he might try, his agitation was perceptible. “I don’t… I don’t know how to tell you that the thought of me losing control and harming you or Padmé scares me enough I’m constantly guarding myself, not without you thinking this is fear and will just lead to the Dark Side anyways. This isn’t the same; it’s not fear of losing something or someone I’m attached to. I’m afraid I’ll hurt someone. I don’t think, anymore, the Dark Side is something I can control if I just try hard enough, it’s something I don’t want to give into.”
He straightened and placed a fidgety hand on the banister. He needed to be moving, some way to work out this tension building within him.
“So, yes, alright. I am still afraid of losing you or Padmé, I don’t think I can’t not be. But I’m more afraid of harming you or her, or anyone.”
