A better position would be to recognize that we are ALL evil and need help to overcome that problem.
That means reaching out to those who have accepted evil as a way of life and helping them find their way back. No one is advocating separating from those who are evil - we would all have to live alone!
But that approach is very different than saying that it is ok for each of us to be evil in our own way.
The Bible makes it clear that there is no one who is good enough to meet God's perfect standards. That's why He had to take on human form as Jesus and pay the price for us. All we need to do is say "thanks" and accept it.
But if we follow your philosophy, then we will never even recognize that we all don't measure up, so we will never seek God's help or take Jesus up on His offer.
That's why it is VERY damaging to make the point you are making.
The first step at an AA meeting is to admit that you are an alcoholic, and accept help.
The first step in this life is to admit that you are evil, and accept help.
We never tell an alcoholic there is no such thing as alcoholism. How will that help her?
And we should not tell any human there is no such thing as evil.
And instead of addressing the issue that made them fit outside of our Norm, we move them even farther and tell them they are wrong.
I am calling attention to addressing the issues instead of labeling them damned. I am not saying, we need to change how we view evil, but instead how we handle evil. We believe people are evil with a snap of the fingers instead of trying to understand the reason we label them evil. Sometimes the best solution is the change our standard, others are to help change the other.
Also look at: "We are humans, all of us. Everyone is evil to some standard out there." I admit, we are evil to some standard out there. In actuality I know that we are all evil to tons of standard out there. There are also standards that we do fit.
If you believe God defines the evil people in the world, then of course there are evil people to your standards. I cannot argue with your fundamental beliefs with how the world runs. I would think you would agree with my approach to address issues instead of your so called, "Ok for each of us to be evil". I don't believe I said that and if I did I am sorry for the misunderstanding. I mean that there is a reason they are labeled, "Evil" by us or our society. Maybe we should address the issues instead of address the person by removing them from our society.
