My specific issue is with moral responsibility, which I believe is out of one's control. (So for example I don't think developers are to morally blame for writing bad code.)
Blame is a messy idea. I'm big on morality, it's how we know what to do next - what we should do, and "should" is a word indicating that a moral idea follows. Without morality I'd be (even more) like a sessile sponge, incapable of action. "Why bother?" is a moral question.
So one can say "I should do XYZ", but this soon descends into blame: "hey you, why didn't you do XYZ?", and that can be mean-spirited recrimination to do with bullying and social pressure, coercion and guilt and labelling people as no good, and main function of the question might not be to seek an answer.
Or, more rarely, it might be an honest enquiry into philosophical differences, or practical problems. Developers shouldn't write bad code. But they do, so we can "blame" them for it. That doesn't mean we should hurl rotten vegetables at most of them. On Wikipedia, I routinely blame people for fucking up an article, but the objective isn't to make them feel bad, it's to fix the article (and to check their reasons, to make sure that I'm not the one with the bad idea). Blame is one thing, but what to do with blame is a separate question.
It's definitely about the way people function, though, about enquiring into their mistakes and motivations. They have "responsibility" in the sense of being expected to respond to "why did you do XYZ?", and even if the answer is "it was inevitable because of the way I am", there's still more practical aspects of the answer ("because I was sleepy, because I was trying to avoid PQR, because I like XYZ") in which to seek knowledge. If we're all autonoma, so what: these autonoma want to solve moral problems.
Historically, ideas of "moral responsibility" are strongly linked with retributive punishment.
If you did something wrong, and you are morally responsible for it, then we are morally permitted (or even obliged) to make you suffer for it (where "suffer" can mean potentially anything from mild social opprobrium up to torture and execution). If you did something wrong, but (for whatever reason) lack moral responsibility for it, then it is morally wrong for us to make you suffer for it. If your moral responsibility is impaired but not completely absent, then it is wrong for us to make you suffer to the normal degree, but it might be justifiable for us to do so to a more limited degree.
But, many people today reject the idea of retributive punishment. And if you do so, it isn't clear how important the concept of "moral responsibility" still is. It is a logically coherent position to accept the evaluative/axiological aspects of morality (the labelling of states of affairs as "good" or "evil" or "neutral", their ranking as greater or lesser goods/evils), and its prescriptive aspects (you ought to do this, you ought not do that, you may do this but you aren't obliged to), while rejecting the concept of "moral responsibility" as misconceived, useless, harmful and/or erroneous.
Yes, but there again you are conflating three separate questions:
(1) Do we have choices?
(2) Are our choices "free"?
(3) Should we be held morally responsible for our choices?
How we answer (1) and (2) doesn't necessarily determine how we answer (3). And if (3) is your real point, maybe you should focus on that, rather than confusing things by conflating it with (1) and (2).
