If Germany had won the war it would have been Britain and Russia that were proved to be entirely wrong - Earnest
So are you arguing that "might is right?".
Who wins a war has absolutely no bearing on the morality of the conflict. The Third Reich was an evil ideology that murdered millions of innocents in the name of Aryan supremacy. The Allies conquered it by the overwhelming use of deadly force. There was no alternative. Even if Germany had won the war it would still have been an evil ideology.
Russia who won the war against Germany represented an ideology that was every bit as evil. History has judged totalitarian regimes regardless of their military success.
it was Britain who was first responsible for concentration camps (in South Africa) in which 20,000 women and children died
What has that got to do with the topic? I'm not representing Britain in the Oppression Olympics.
Let's try again to get back to the actual topic...
1 - Sometimes saving lives of innocents requires the use of lethal force. Whether that is protecting your family from criminals, stopping armed terrorists in a city centre or defeating an army bent on genocide.
2 - The Watchtower forbid the deliberate taking of a human life in all circumstances.
3 - Many ex-JWs continue to view the Watchtower' position as a virtue.
