Yes - I am not saying that JRRT himself was anything less than saintly, or did not struggle with the issue.

My issue is with the Wikipedia article's heavy identification of JRRT's personal dilemma with the Roman Church and its doctrines. Historically, for that Church - one could just assume that the orcs were Protestants, so slaughtering them was perfectly okay. https://en.wikipedia.org/wiki/French_Wars_of_Religion
