To be fair, Kate inexplicably didn't get round to telling him that he couldn't come back, but he didn't on the strength of it appear to be acting at his finest... did he request passage for anyone other than Juliet and himself? Why was he so blithely happy when he knew his fellows were still suffering back on the beach? Surely his own promise of freedom can't have made him forget all that? And who's to say there'll be anyone alive for him to rescue? He knows how unsafe that environment is.

Still, we can't have all the info yet. I sincerely hope there's a lot of stuff we don't know that'll make his behaviour clearer.
