Show me where in the 20th century God intervened to stop the deaths of over 150M people at the hands of totalitarian regimes. Evil as a force doesn't exist. It is what people become when they act against the law of nature.
Evil doesn't exist? If evil doesn't exist, then neither does right and wrong. That makes you a moral relativist a la Marquis De Sade ("what is is right"). How sad for you. You don't have a logical leg to stand on. The law of nature?! Show me the law of nature that says that murder is wrong. Where Can I find it? Your argument is illogical.
First you talk about evil then you say it doesn't exist. Since evil doesn't exist, then it can't be evil or wrong to kill 150M people! Make up your mind! Either evil exists or it doesn't. You are contradicting yourself.
Another problem you have is that that EVIL cannot exist without a standard. What is that standard? huh? The very existence of evil proves there is a God - a Good Standard. Nature provides no standard! Where is it? I don't see it - can I find it by looking at a tree or a dog?
