[ Pirates of the Caribbean] Why did Becket order the Kraken to be killed?

 

Lord Beckett, the antagonist of the movie, who controls Davy Jones, decides to ask said Davy Jones to kill his incredibly powerful sea-monster: the Kraken.

Since Beckett controlled Jones and since Jones controlled the Kraken; Beckett controlled the Kraken.

It would have been a great addition to his army; in fact making it almost unbeatable.

why kill him?

Beckett controls Davy Jones **for now**, with no idea how long he can put leverage on him before he betrays him.

The Kraken on the other hand has been  a dangerous hazard to every ship from a filthy pirate to a rich merchant, including the Royal Navy.

By ordering Jones to kill the Kraken he achieves three important things at once:

1. He tests Davy Jones loyalty 

2. He gets rid of a well known and feared sea hazard, making both his regular job as a Navy officer easier and helping merchants to bring more revenue to the Caribbean.

3. He severely weakens Jones Forces in case of his inevitable Betrayal.
