Clockwerk let Sly venture into his lair so Sly would find the captured Carmelita. Clockwerk knew that Sly would try to save her so he used her to lure him into the gas chamber. Once Sly succumbed to the gas we can assume that Clockwerk thought him to be dead already. Unbeknownst to Clockwerk, however, Sly was saved by Bentley and was able to advance further through the lair.
