It is an assumption that there is always one single dimension for assessing persons and their actions that has canonical priority. This is the dimension of moral evaluation; "good/evil" is supposed always to trump any other form of evaluation, but that is an assumption, probably the result of the long history of the Christianisation and then gradual de-Christianisation of Europe, which one need not make. Evaluation need not mean moral evaluation, but might include assessments of efficiency, ... simplicity, perspicuousness, aesthetic appeal, and so on.
