There's a website that has reprint of lots of old watchtower, and I happened to look at the first one, dated July, 1879.

In a supplement to the issue, by C.T.Russell, he offers a suprising (to me) viewpoint which seems to echo the arguments of many 'apostates' here, namely, that to kill billions at Armageddon would be unloving and unscriptual.
We reasoned that, if Christ's coming were to end probation, and bring irrevocable ruin upon ninety-nine in a hundred of mankind; then it could scarcely be considered desirable, neither could we pray with proper spirit, "Come, Lord Jesus, Come quickly!" We had rather request--much as we should "love his appearing"--that he remain away and our sufferings and trials continue so that "if by any means we might save some." Not only so, but great masses of scripture referring to the Millennial glory and teaching that "All nations which thou hast made shall come and worship before thee," &c., &c., would be left unfulfilled if at His coming there should be a wreck of matter and a crush of world.
Am I reading this right?
