乱暴にされているのに....

Got the sentence above from a book. From what I understand, に marks the doer
in a passive sentence. In other words, the sentence above would translate to
"done by violence", which doesn't makes sense to me. What is this に trying to
mark here?

particle-に
に in passive sentence
に, like most Japanese particles, can have a number of possible uses.

In a passive sentence, に _can_ mark the actor (similar to "by" in English),
but in a passive sentence, に can also be used in any of the same ways it can
be used in other sentences, too, so just because it _can_ be used that way
doesn't mean it necessarily _is_.

In this case, as you noted, interpreting it as indicating the person/thing
doing the action does not make a lot of sense, so that's probably not the
right meaning. What is the right meaning? Well, 乱暴 can be an adjective
("violent"), に is commonly used to form adverbs from adjectives ( _adjective_
+ に --> _adverb_ ), so without other context this seems like the
straightforward interpretation:

> 乱暴 ("violent") + に (adverb) --> 乱暴に ("violently")  
>  乱暴に ("violently") + されている ("is being done") --> 乱暴にされている ("is being done
> violently")
