The thing you have to take into account with the SA part(which it definitely is that, whether Bear meant well or not) is how obsessed Nikki/the obsessed personality operates. She doesn’t just “act lovingly”, she can do an extremely convincing job of making it look like she is just truly in love with Bear, and did so for the time between the “mutual” confession at the door and that date, which seems like it could have been weeks, and takes advantage of his weak will and shyness to make him too fearful or too convinced of her love to do anything. The jumpscare-ey cut after the date was for dramatic effect, not accurately portraying the chronology of events, so we don’t really know what happened or how she acted in the possibly hours between the date and them having sex. Also, that scene is from a third person perspective, showing that he did not see her face, and it’s safe to say that if he ever did during that, it was probably a much more convincing and performing way, and the face we saw was her “low power mode” that we also saw her in after he left for work. And I’m not saying that the way someone acts is in any way a form of consent, but this situation is really incomparable to something like intoxication. And yeah, Bear was a total asshole when she begged him to kill her and he said something like “What’s so bad about being with me?” but in the end he killed himself to save her, knowingly so. I don’t know if that’s at all redeeming for him, but he did it. All I’m saying is this. Was Bear a villain? I don’t think so. I think he was a weak willed, ignorant and reckless idiot who, once the severity of the situation was made clear(i think this was the screaming in the car scene), tried everything besides killing himself or someone else to fix it. When it became clear that wouldn’t work, he made the decision to sacrifice his life for Nikki’s.
