[Keeper of Dol Guldur]

That's what I was sort of getting at.

It wasn't Boromir's Pride, or Envy or other sins that led to his spell, if anything his sins and virtues were balanced out fairly well, as they should be in all men, but a lack of virtue was what let him lose it, and so it was totally not his sins that did him in, but his lack of virtue.

Even if it was only momentary, it was enough to screw all sorts of things up.

He got shifted off balance for like ... a moment, and it took a long time for those tensions to even build up, and then when he finally lost his cool a little bit, whammo! The Fellowship is broke and he ends up dead.

But like I said, he was very balanced before, and even though he got 'unbalanced' for his sudden spell with Frodo, after he fell flat on his face and lay there for a while and cooled off, he was balanced again.

Honestly ... after that, and seeing firsthand what the Ring could do ... I think he would probably have actually been safer around Frodo and the Ring than he had before, when he had doubts and misconceptions about it's power.
