Atheists are the reason for some of the most brutal murders around, way more than Christians. Consider Stalin and his 30 to 100 million (we may never know for sure), Hitler and his 20 million (he wasn't Christian although he went to mass at times), and all the Southeast Asian atheistic communistic leaders who killed many millions of their own people.
If Bible were law, there would be peace among those who accepted it as law. Take a look. It's right in the Bible.
Anyone who compares the opposition to Hitler, automatically loses any argument they tried to make.
Hitler didn't kill any(?) Jews himself, other Germans did that... and guess what... those Germans were mostly Christian, same as America!... that means Christians did all that evil murdering... get your facts right...
Religion is the force responsible for the vast majority of wars throughout history. Christians are solely responsible for what we commonly refer to as "The Dark Ages"... 300 years of crusades, and inquisition!
Just read the bible... how many nations did the Jews attack? "The Promised Land", "The land of milk and honey", was such because there were people living on that land... they were farmers and bee-keepers, which is why they had milk and honey... until the Jews killed them all and took their milk and honey... that's how religion operates... they kill and take people's stuff... all the while claiming moral authority directly from God Himself!
You play with semantic-like ideas.
In addition, the Jews who attacked and killed people who didn't believe in God, were doing those people a favor. Here's how.
God is just. He will punish wicked people according to the quantity and quality of their wickedness.
Now imagine as an example that you were 20 years old, and had been wicked all your life. By the time you were, say, 50, wouldn't you have done a whole lot more wickedness? If you die at 50, you have a lot more to be punished for in Hell than you would have if you died at 20.
So, here you are, 20, and out fighting the Jews in battle. You die in battle. You have a lot less to pay for in Hell than if you died at 50, peacefully. The Jews have done you a favor by killing you.
If you had wanted to convert to God and be with the Jews, you could have left your family and the war, and have waited for peaceful times to contact the Jews to convert. They would have let you.
Here you are right now, fighting against God. And death in youthfulness might even be gone for you, so that you don't build up a larger amount of wickedness to be punished for in Hell. Turn to God so that He can wipe your wickedness away, so that you don't have to pay for it in Hell. Such is a free gift from God, if you turn to Him.
Your choice, of course. God holds it open for you until the time of your death. Do you know when that will happen, exactly... the day of your death, I mean?
