Responsibility Involving Free Will?

"In that way too it was in the power of an unjust or dissipated person at the beginning not to have come to be that way, which is why they are that way willingly, but once they have become so it is no longer possible not to be so" (1114a 21).

I find this quote very interesting for Aristotle to write. I agree it is the fault of an unjust and dissipated person to become that way. Do I feel like once they have become that way they can't go back? That's something I've always questioned. Once someone is a certain way, I don't believe they can change without the help of God. I also feel these people are more susceptible to fall back into the way they were, which makes me feel like they are still that way at heart. I understand God can change people, and I truly believe He can, but it's easy to be weary of one who has proved themself to be an unjust person.

Aristotle, however, doesn't address free will in book 3. Free will is the power to make a decision without the constraints of external circumstances. Aristotle overlooks this entirely and only focuses on those actions that we are responsible for. He believes that we are not held responsible for actions we do out of ignorance or impulse. Where is the definition that states what we are responsible for? And also, ignorance or not, an action is an action and you're responsible for what you do. I understand the argument of being under the influence, but one chooses to drink. If it was a forced act of someone making one under the influence then I see how it wouldn't be their fault. However, in this case you can also find choice in the groups you hang out with or situations you put yourself in. I will admit that there are situations that are totally out of your control and in that case there would be an unwilling action.

I feel Aristotle leaves an empty case here for fear of defining what responsibility itself is. This leaves us confused to what we are held resonsible for in relation to our actions we are fully aware of and those we are ignorant of or have acted out of impulse on. Not sure i agree with this vague claim, nor do I feel free will can be completely left out of these arguments.
