Honestly no...not even a little bit. What do you even mean you want to play evil without killing anyone? That makes literally zero sense. I can understand the idea that there's no kingdom to rule over if you burn it all to the ground, and personally I prefer corrupting evil style much more over stabbing but evil isn't about pacifism. You sound like you have no idea what you want to do. The Dark Urge is just an extra option on top...a more fun way to go about the killing of some enemies you'd probably have to kill anyway or a means to get extra power from killing some NPCs that you might otherwise not be able to do much or anything with and some of the gear the Dark Urge path rewards is insanely good.
I thinky misunderstand "see death as a last resort or a necessity, never as a goal or as fun". It means they kill if there is a reason or it is unavoidable. They do not have a deeper urge to do so. The Dark Urge is all about killing, I can not put myself in a character that is about killing, because I can't play it.
And I am still certain that you will not have the same options as Dark Urge than as Tav. That you need to resist with a saving throw makes sense and keeps them different enough.
I know what I want to do. For a good run and also for an evil run. Neither will be overly into murder. Because I fail to see the appeal of even getting such an option. I kill Astarion for trying to drink my blood and not for some murderous urge.
The Murder-Theme simply does not appeal to me, I do not quite understand how that makes me into someone that does not know what he wants.
