deontological responses ... arise from some sort of error, or poor thinking.
I don't understand the complaint. Deontology is simple: you just apply the fixed rules. If in a particular situation the fixed rules lead to an undesirable outcome, that's too bad but that's how deontology works -- it is explicitly NOT consequentialism -- and that has nothing do with "poor thinking".
or as generalissimus Stalin would say: "No man, no problem"
