Some blame racism but could anger be the cause of Eric Duncan’s death?

Some have pointed to racism in the death of Eric Duncan.  My question is could it be something other than racism. Could it be that doctors and nurses were angry at Duncan for coming back into the United States knowing that he may be sick and thus endangering them all? – See more at: http://www.africanamericanreports.com/2014/10/some-blame-racism-but-could-anger-be.html
