That's certainly what they're having fun with, every action he's done, kept him alive, rocking him, etc. can be read as genuinely caring, ....or he's just making sure he's keeping him alive, to collect the bigger bounty for himself. Of course there is no subtlety in that pretty much the one thing we know about this Mando, is that he too was once a foundling, separated from his own, and saved by (so far a mystery) somebody. So if you find yourself projecting the same empathy onto his actions, it's cause, they want you to. I doubt it, but they can just as easilly, and somewhat cynically flip it on us, and do the: he is a Bounty Hunter after all, so what were you excpecting.
