Is the classification of the four kinds of miscreants in Gita 7.15 strict?

From: T AMIT KUMAR

prji in BG 7.15 it seems that Mudhas,maya apahrita jnanis and asuris all three can also be called naradhamas because all of them miss human chance.also i feel that every category can have the quality of other categories.so is it a strict way of classification of the people who are duskritinas?can you pls explain.
