Amplifying? I'm not sure about that. It seems to me that you were saying that none of us, in our own ways, are better than Hitler.
Now, I grant you, before God, sin is sin. But the bible seems to indicate that God will punish accordingly, what each and every person has done (Psalm 62:12; Proverbs 24:12; Jeremiah 17:10; Ezekiel 18:20, 30; Romans 2:5–16; 1 Corinthians 3:8, 11–15; 2 Corinthians 5:10; Colossians 3:23–25; 1 Peter 1:17; Revelation 20:12).
So, we could probably debate until the cows come home who is the more unrighteous; Hitler and his Nazis, or those who, hating war, went out anyway to stop Hitler and his Nazi atrocities coming to their own shores.
There are times and places in this life that Christians are called to turn the other cheek, to go out and risk life and limb for the sake of the gospel.
But one could just as soon argue that because good men took up arms, that nations were founded on biblical principles and generations were raised with the free knowledge of God. Were you aware of just how much America does in the area of aid and missions...based purely on the Christians churches? How many missionaries have been sent forth from your Country alone?
The problem, as I see it, with saying "is anyone better than Hitler, as we're ALL sinners?", is that, while techincally true, in a biblical sense, you are blurring the line between right and wrong. Born again believers are still sinners. ISIS members are sinners. Thus, we are the same. Wrong, absolutely wrong. There is a divide, a massive, massive divide. First, the bible is clear that morality exists; right and wrong. The common grace of conscience proves it, and we have daily evidence that those belonging to ISIS and other terrorists groups don't have that. They happily rape, torture and kill. The second difference is, of course, the hope born again believers have in grace, and the new life that becomes more and more evident in their lives as they go along. And because of Christ, we have right standing before God.
