Reslight's comments do highlight a big reason why I personally don't hold Russell as responsible as Rutherford and subsequent WT leaders - there was freedom to disagree, and the Bible Students didn't claim to be organized "Theocratically", a notion which originated with Rutherford.
Without Rutherford, I think the entire history changes most significantly than it would have by subtracting Knorr or Franz or any other leader. In other words, by subtraction, removing Rutherford from the equation would have, in my theoretical scenario anyway, changed the organization the most because it would not have become so autocratic.
So yes, Russell started the whole thing, and the noose of 1914 is still attached, but I don't think that he in any way envisaged what we've seen from this religion since his passing.
