It’s a tool like a hammer. You can use it to do good or bad things. Like any form of communication. At least NVC is better at empowering people to get their needs met, compared to the alternatives.
But, OF COURSE nonviolent communication empowers the speaker. It’s about articulating the SPEAKER’S observations, feelings, needs, and recommendations and putting them in an order where you can understand the context.
If you don’t communicate your feelings to other people, they will find it difficult to empathize with you.
The receiver empathizing with the user is not considered by users of NVC as an end in and of itself, but rather a means towards an end. The real objective is getting something from them other than their empathy.
