If I recall correctly, canon!Ron has admitted to fantasizing about murdering Draco on several occasions. The one that comes most readily to mind was in book 4, when they were discussing Durmstrang’s location in the far north, and Ron comments wistfully about how easy it would be to push Draco off a glacier and make it look like an accident.
I’m pretty sure even canon Ron would at least say he approves of killing Draco.
