I think that interpretation conflates civility politics and banality of evil. One axis about decorum and appearance. Those who look and act like "good and decent upper middle class people" always get the benefit of the doubt where others do not, even when that appearance, like with Eichmann, completely falls apart on closer inspection. The other axis distinguishes between people who have a highly ideological agenda and execute on it (evil) and those who are mostly unthinking cogs in a machine of destruction (banal evil).
