Thanks for the comment
Well, the scriptures are not clear. They don't say. That is the case with most controversial passages, it doesn't say, so people try to make it say to support their position.
It is interesting though if David were this all-powerful brute who could do anything he wanted … why was there a need to cover it up? If he were this monster … he could have just shrugged it off, denied being with her, and she would have been in worse trouble.
That to me means there was some emotional involvement with them. She also became his “main” wife later.
The story is about David and his wrong … it doesn't tell us what other people were doing. I tend to see her as either passively going along with it, or a willing participant because it was covered up, and because she later became his main wife. But both are reading something into it that isn't there naturally.
There are many other scriptures that speak more powerfully to power dynamics, abuse of power and even rape.
