2. Hm? No. The state of mind is completely relevant to culpability, just as the sentence above says. Remember, culpability and moral responsibility are the same things. Just different ways of addressing it.

I think we need to get through the misunderstanding in question 2 before we can go any further.

No misunderstanding here, your words are perfectly clear.
