Dishonest
Although... I make it sound like I've got nothing to do with Fred's current sorry state, and that's dishonest.
To bring his soul back, I had to make it succumb to my succubus self. I promised him I wouldn't, er, do my part. I also told him we'd talk about it later.
But I never did. I left him with the dangling prospect of me potentially snatching his soul from his trembling fingers, so to speak.
That probably didn't help.
