No, Bastila thinks the Jedi Masters have established the enclave. She doesn't know they're dead yet.

Also, Carth won't even know of the Jedi Enclave, he'll be told that there's been sightings, so he'll want to get to Dantooine, the second he's returned from a Republic mission which Bastila has accompanied him on (in hope of finding some trace of Revan). So he won't be 'aiding' the Jedi. It'll be purely out of wanting to find Revan.
