But Harry just shook his head. "That's not the responsible thing to do, Hermione. It's what someone playing the role of a responsible girl would do."

I don't know that Harry or Eliezer make this distinction, but I'd say that it's important to recognize a difference between judgments about yourself, and judgments about others.

When Harry talks about heroic responsibility, he's speaking from the first person perspective (at least). He has his values, and he wants them achieved regardless of the good/bad behavior of others.

The usual responsibility we talk about is second/third person - your fault/his fault. It's about negotiation with and judgment of others. This is where someone judges someone as "fulfilling a role" - it's a thumbs down or a thumbs up on another person, according to the rules of interpersonal behavior you approve of.

We can treat ourselves as objects, and apply that thumbs up or thumbs down to ourselves as well. That is useful in understanding the reactions of other people to you, in negotiating and otherwise interacting with others, and asserting your values in terms of that negotiating and interacting, but it's a category error to confuse that interpersonal thumbs up/thumbs down applied to yourself as the proper way to choose your actions. I'm pretty far down the path of just considering it a neurosis.

Choose your actions to achieve your values, don't choose them to achieve good boy status.

However, it seems to me that what Harry has described as heroic responsibility is a conflation of the 1st and 3rd person perspective. He still judges his own good boy status in the 3rd person, but he does it from the perspective of behaving properly from a 1st person perspective. He is a good boy if he chooses the best actions to achieve his values, and a bad boy besides. Actually, he seems a little worse than this, in that any failure makes him a bad boy, which is an impossible standard.

(EDIT: jimrandomh makes a similar point)

He is maximizing his utility part-function: people should not be harmed. If I know of a situation such that: Someone will be harmed if I do nothing; They will be harmed equally if I tell the authorities; If I intercede with my allies, they will be harmed less.

The first two actions are equal. The third one is better. The ability to determine the actual consequences of future actions is magical. Fortunately for Harry, he has access to magic. I expect Harry to develop a procedure where he makes several plans, checks for a note indicating which plan he should use and any changes he should make, executes the plan, and then time-turns a note back to himself indicating which plan worked and any retroactive changes to it, then assists himself if needed.

Something tells me that the note would be more likely to say something like "DO NOT MESS WITH TIME".

Really? Is that what happened just before he got the time-turner?

As I recall, he was trying to demonstrate a way to solve any problem in C time, where C is the time required to falsify a proposed solution. That's different than realizing that you have a higher chance of destroying Azkaban in an hour if you help yourself eight times.
