To start, I want to remind you of a few things vital to the theory:
K'rul made the warrens with his own blood.
Memories of Ice Bantam paperback page 327 said:
The Crippled God is chained to Burn with the power of K'rul's blood.
(Gods like Fener, Cotillion, Hood, etc., participated in the chaining.)
This connection between K'rul, Burn and the fallen god makes it possible to poison the warrens and Burn.
(This is speculation on my part.)
The chained one wants to get free.
(This is speculation on my part. Could be it is stated directly somewhere.)
The Crippled God needs to remove the power of the warrens in order to get out of his chains.
(This is speculation on my part.)
Through the Crippled God's influence, there have been at least four disparate attempts at human extinction.

2. Poleil's pleague in Seven Cities, killing (supposedly) millions of people.
3. The Empire of the Tiste Edur, who were sent out to slaughter in their search for Champions.
4. Karsa Orlong, who was "lead" by the Unbound to make an army of Teblor to destroy all "children".
Notice here that the Edur did not slaughter the Letherii. I believe this is because they (the Letherii) use Elder magic, and not the warrens.
The Elder gods do not want to destroy the Crippled God.

'Yes, you've already said something to that effect. They are opposing the Crippled God, and one cannot find fault in that.'
'Are they? Sometimes I'm convinced... other times,' he shook his head.
***I believe in destroying the chained one, they would also destroy K'rul and the Warrens. This is speculation on my part.***
Karsa Orlong will do something horrific some time in the near future.

There will be a big turning point in Toll the Hounds.
The Bonehunters Bantam paperback page 926 said:
'Because,' she said, 'I know where it shall lead.'
'The future unfolds before you, does it?'
'Never clearly, never completely. But I can well sense the convergence ahead - it shall be vast, Mappo, more terrible than this or any other realm has ever seen before. The Fall of the Crippled God, the Rage of Kallor, the Wounding at Morn, the Chainings - they all shall be dwarfed by what is coming.
Now consider this:
Why would the Crippled God want to wipe out humanity?
Who uses the warrens?
What is the big convergence in the upcomming installment of the Malazan book of the fallen?
This is where my crazy theory comes in:
If all humans are killed, all worship will cease and the power of the warrens will diminish into nothing, which will by default free the Crippled God. This is what he wants.
Now, we can't have humanity removed from the world (I just don't see it happening), so instead, Karsa Orlong will destroy K'rul, and in so doing, destroy the warrens and free the Crippled God from his chains, curing Burn.
-Now, to see the theory crash and burn at your mercy
