Let's consider the situation. The Ring had at that time lain on the bottom of the Anduin since Isildur dropped it [insert precise length of time which I can't look up now, being 60 km away from my copy of LotR]. Sméagol and Déagol would be its first chance in many centuries at getting any closer to its maker. Even if it was at an all-time energy low I could imagine it mustering what little power it had in one all-out activity burst, a desperate attempt to get on the finger of a convenient and malleable bearer.
Also, we have a direct contest between two antagonists for possession of the Ring. We shouldn't, in my opinion, look to Boromir or the Council of Elrond for parallels, but consider Frodo's reaction when Bilbo just asks to touch the Ring in Rivendell, or when Sam offers to carry it for him. His first impulse (immediately suppressed and regretted, of course) is to strike, lash out, claim possession. Magnify this impulse enough, and you get Sméagol killing his friend.
But Frodo still killed neither Sam nor Bilbo, even though he had carried the Ring for months then, whereas Sméagol had only just seen it for the first time when he killed his friend. I therefore concur with
Inzil that Sméagol's character is key. He had a long headstart in his decline into evil even before he took the Ring. If Boromir didn't just backstab Frodo when they quarrelled it was because even then he was a nobler man than Sméagol had ever been.
[I must, however, object to this:

Nobody is mean, sneaking or anything of the like
from their birth, and I would find such a statement atrocious if made IRL of a real person. Just saying.]
