Well let me start by saying that murdering the DVERGR as you put it is currently part of the game like it or not. As an early access game things change and will continue to change. For me I went through and got 3 from the settlements my 4th and 5th came free as I stood back and watched seekers destroy them so I didn't need to. So in a way it's optional to kill them. If you don't wanna off them yourself just keep luring seekers to them, let them kill the dvergr for you if that's what you wish. Good luck 👍🏽 💓
