Question

 $('#remove').click(function() {
        var foo = [];
        $('#FeatureLists :selected').each(function(i, selected) {
            foo[i] = $(selected).text();
            alert(foo[i]);
            if (foo[i] != "Add" )
                return !$('#FeatureLists option:selected').remove();
            if (foo[i] != "Edit")
                return !$('#FeatureLists option:selected').remove();

First of all, based on your sample code, the array foo is does not appear to be needed. Secondly, the if statement needs to include all the items that need to be excluded with OR conditions as shown below:

if (foo[i] == "Add"    || 
    foo[i] == "Edit"   || 
    foo[i] == "Delete" || 
    foo[i] == "View")
{
     return;             
}
else
{
     $(selected).remove();
}

Try this as well. Simple one line code and slightly faster

$(document).ready(function() {
         $("input").click(function(event) {
            var foo = [];
            $('#FeatureLists :selected').each(function(i, selected) {
               foo[i] = $(selected).text();
               if (foo[i] != "Add" && foo[i] != "Edit" && foo[i] != "Delete" && foo[i] != "View") return $(selected).remove();
            });
         });
      });
