How inimitably rude you are to him.

Rude? Not really. I said:

An incredibly modern character, in Gollum we see a creature beset with failings so unimaginable, we can see there is no hope for him, and yet we see a creature we simply cannot just hate.

I'm fond of Gollum, and I'd defend him against any claims that he was 'inherently evil'. I see Gollum as a character to appeal to the modern, less certain mind. He cannot be 'cured' of his addiction, and cannot be controlled or made acceptable to 'society' in general. Yet Tolkien shows us how he is not to be hated. He tells us to think carefully:

'But this is terrible!' cried Frodo. 'Far worse than the worst that I imagined from your hints and warnings. O Gandalf, best of friends, what am I to do? For now I am really afraid. What am I to do? What a pity that Bilbo did not stab that vile creature, when he had a chance!'

'Pity? It was Pity that stayed his hand. Pity, and Mercy: not to strike without need. And he has been well rewarded, Frodo. Be sure that he took so little hurt from the evil, and escaped in the end, because he began his ownership of the Ring so. With Pity.'

'I am sorry,' said Frodo. 'But I am frightened; and I do not feel any pity for Gollum.'
'You have not seen him,' Gandalf broke in.
'No, and I don't want to,' said Frodo. 'I can't understand you. Do you mean to say that you, and the Elves, have let him live on after all those horrible deeds? Now at any rate he is as bad as an Orc, and just an enemy. He deserves death.'

'Deserves it! I daresay he does. Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends. I have not much hope that Gollum can be cured before he dies, but there is a chance of it.

Tolkien also tells us how a creature we might think of as 'evil' may in reality not be so far removed from our own good selves:

'I think it is a sad story,' said the wizard, 'and it might have happened to others, even to some hobbits that I have known.'
'I can't believe that Gollum was connected with hobbits, however distantly,' said Frodo with some heat. 'What an abominable notion!'

'It is true all the same,' replied Gandalf. 'About their origins, at any rate, I know more than hobbits do themselves. And even Bilbo's story suggests the kinship. There was a great deal in the background of their minds and memories that was very similar. They understood one another remarkably well, very much better than a hobbit would understand, say, a Dwarf, or an Orc, or even an Elf. Think of the riddles they both knew, for one thing.'

'Yes,' said Frodo. 'Though other folk besides hobbits ask riddles, and of much the same sort. And hobbits don't cheat. Gollum meant to cheat all the time. He was just trying to put poor Bilbo off his guard. And I daresay it amused his wickedness to start a game which might end in providing him with an easy victim, but if he lost would not hurt him.'

'Only too true, I fear,' said Gandalf. 'But there was something else in it, I think, which you don't see yet. Even Gollum was not wholly ruined. He had proved tougher than even one of the Wise would have guessed--as a hobbit might. There was a little corner of his mind that was still his own, and light came through it, as through a chink in the dark: light out of the past. It was actually pleasant, I think, to hear a kindly voice again, bringing up memories of wind, and trees, and sun on the grass, and such forgotten things.

'But that, of course, would only make the evil part of him angrier in the end--unless it could be conquered. Unless it could be cured.' Gandalf sighed. 'Alas! there is little hope of that for him. Yet not no hope. No, not though he possessed the Ring so long, almost as far back as he can remember. For it was long since he had worn it much: in the black darkness it was seldom needed. Certainly he had never "faded". He is thin and tough still. But the thing was eating up his mind, of course, and the torment had become almost unbearable.

Even Gandalf displays some hope for Gollum where I do not - I would not know what to do with him, though I could certainly not kill or hurt him.

The text you quoted does indeed show that redemption was possible for even the most wicked of characters in Middle Earth; and I indeed think it was possible that Gollum could have been redeemed. But still, was he redeemed? Did he have the chance to be redeemed? Was falling into the Cracks of Doom with the ring enough to redeem him? I certainly hope he was 'saved', I'm rather fond of Gollum.
