Again, you seem to be stuck on the negativity of one man and his issue. He is dead and they are grieving.
How about focusing on the bigger picture?
Well, I think most of us are capable of holding two thoughts in our heads at once: (1) We are concerned about Ebola. (2) We don't approve of this man and/or his family's conduct.
I don't think the evidence regarding whether Duncan came here knowing he was probably going to get Ebola, and wanting to be in the U.S. for medical treatment, is well-established. The evidence seems mixed, and I've read varying explanations of why he came here at this time.
