I agree with everything said here I think. But I would also like to add the other side of the equation, that when presented with clear proofs or you are reminded about knowledge you know deep inside, but that decide to deny and reject it, this disbelief is unjust and unethical too.
Depending on the weight of what you are denying and it's purpose, it can be an extreme injustice. When you oppose a truth simply because you dislike it, despite being present clear proofs, and prefer blindness over sight, it's an injustice too.
Following what you have no knowledge of is to be condemned, and attributing to God for example what you don't know is a great injustice, while also disbelieving in clear proofs or denying knowledge you know when reminded, is unethical too.
