Actually, I mentioned that you had mentioned (something similar to) the duty to rescue thing. And that I'm not implying that you consider him innocent. ._./ You might want read my post again. ;D

My main point is that, while Zeref cannot be held completely responsible for the Tartaros (and other) incident(s), he does share quite a bit of the blame. Maybe not even the larger part, but certainly a large part. Contrary to the general opinion that he is virtually innocent. Again, not saying that this is your opinion, but it is the prevalent view.
