As you point out, worry can reach the point of sin, and sin is sin.
Of course, this thread is a discussion of a disease that has laid waste to whole regions. That disease is not spread by worry.
The church has been at the forefront in caring for people who have the disease, your church is probably involved and if it isn't, it won't be hard to find one that is.
And the church is in the forefront of reminding people that their individual behavior matters, not only when you face judgement but in this life as well. A man who is not faithful to his wife sins before God, and damages his marriage, but in areas where the disease is common he also risks killing his entire family. If you love people you have to tell them that.
My original point was that it does no good to know what the bible says unless you are willing to love people the way Jesus loved people. Jesus loved those who were outcasts. HE loved those who society rejected. If we are to follow Jesus we must do the same and give of ourselves and resources.
