[Letting the past burden him is all that Castiel seems to be capable of as of late. His life revolves around trying to repent, and he isn't certain what he would do if he didn't have that. Still, it is kind of Saki to try and reassure him, despite her fears.]

I promise you I have no intention of using my power to hurt anyone innocent. [There are other situations where he might need to use them, but he isn't one to attack anyone for the sake of it.]

The events here may force my hand, but other than that, I focus more on trying to atone for those past mistakes.

[And this situation has offered him another opportunity to do that. Castiel pins Saki down with his gaze.]

If you're ever in need of help with anything, you can contact me and I'll do anything in my ability to be of assistance.
