I don't think religion had much to do with it, but looking to the old testament I think God wouldn't have any problem with killing tens or hundreds of thousands of people at least. God certainly did several times. : /
And Columbus was the governor of Hispaniola and atrocities were common while he ruled.
When God made the world, He did it for His own reasons. Among them were for His own pleasure, and for ours. The world was a thing of strong and delicate balance at the same time. Who can second guess why God made it this way? Perhaps it is the best way to make it.
When man listened to the devil and ate the fruit, he broke the whole base system for the universe - love of God, and love of fellow man. How does that work, breaking the love? Think of how you feel when your kids that you have done everything for and have given everything to, simply rebel and spit in your face, and turn away.
You don't stop loving your kids. You still love them and try to help them out of the messes they get themselves into. God is like this, as well.
This universe is down the tubes because of what man has done... sin. Christianity started back at the beginning to save man, even though it wasn't called by that name back then.
God allowed Himself to be wiped out by the sins of man. He did this through the death of His Son, Jesus, the Christ of Christianity. Some of you may, out of love, have allowed your rebellious kids to wipe you out. God is GOD. He can't be destroyed, even when He is wiped out. Ultimately it is His kids who will wind up destroying themselves when they rebel.
There is going to be a resurrection, and a final judgment for all. Those who remain rebellious towards God will be destroyed. The punishment in that destruction will be meted out according to the amount of rebellion that they perpetrated while they lived this life.
NOW THINK ABOUT THIS. When God destroys a rebellious nation here, a nation that will not turn to Him and to His Christianity - the only way that they can be saved - God is doing them a great big favor. How? He is keeping them from sinning more. This way their punishment in the final judgment will be less. In other words, they are the ones who are really destroying themselves by resisting God, Who cannot be resisted. God is simply making their ultimate pain to be less by destroying them from this life.Perhaps you never had the opportunity to stand on ice. But if you have and did, you know how slippery it was at times. Sometimes a bunch of kids will pile themselves up on the ice. If you try to push them, you will only move yourself. You will slide rather than the heavy pile of kids. That's what it is like pushing at God in rebellion. He doesn't want or need to fight you off. You can't move Him. You simply destroy yourself. If it appears that you die young because He steps in and squashes you, thank Him tremendously that He didn't let you destroy yourself in the final judgment in a worse way than you are doing, by rebelling against Him even more in this life.Rather, turn to Him. He doesn't want to see you destroyed, either with or without His added push. He is willing to forgive, any time, anywhere, any way, for any sin, except the sin where you
LOCK yourself into not accepting Him, where you can't be changed to faith no matter what. Most unbelievers do this when they die.
Read this slowly, and see how you pass your unbelief in Christianity on to your kids, adding to your rebellion. This is what the Muslims and other religions do.
Christians may use Christianity incorrectly at times. Often they do it without knowing what they are doing. They are people. You can expect it from them just as you might expect it from anyone else.
The answer to the question of what would have happened if there were no Christianity isn't clear, but it is probably one of two answers:
1. There wouldn't be any universe, earth or people;
2. All would have been destroyed in the anger of God right at the time of the fall into sin in the Garden.
