The most chilling lines in The Lord of the Rings...

From The Two Towers "Shelob's Lair" (slightly edited):

‘We’ll see, we’ll see,’ Gollum said often to himself, when the evil mood was on him, as he walked the dangerous road from Emyn Muil to Morgul Vale, ‘we’ll see. 

'It may well be, O yes, it may well be that when Shelob throws away the bones and the empty garments, we shall find it, we shall get it, the Precious, a reward for poor Smeagol who brings nice food. 

'And we’ll save the Precious, as we promised. O yes. 

'And when we’ve got it safe, then She’ll know it, O yes, then we’ll pay Her back, my precious. 

'Then we’ll pay everyone back!’

Then we'll pay her back... Then we'll pay everyone back!

These sentences from Gollum/ Smeagol chill me, deeply, whenever I read or hear them. 

Here we have encapsulated the power of that most evil of motivations: spiteful resentment. 

The self-righteous, insatiable, lust for revenge.

The will to hurt, to destroy every-one, every-thing... all of divine creation.
