its less that at level six you think that the laws are immoral, its more that at level six what you think is right isn't based on outside principles or personal consequences to you, isn't based on avoiding punishment, etc. it is about a personal conception of what is fair and what is just. The principle guides you, consistently (At level five you are a little less consistent and more contingent on the social contract.) a minority of adults function in the post conventional stage, and of those very very few are at level six to the point where there isn't much empirical evidence for it being common.

i say this in another post but imo a really easy way to conceptualize level six ethics is Martin Luther King, Jr.s "Letter From Birmingham Jail," which essentially explains his logic behind nonviolent resistence. in reality king was probably closer to a 5 and a half-- he was far from a perfect person who, for example, cheated on his wife in a way that wasn't very consistent with his stated principles. but here, in this issue, his position is one of universal rights and wrongs that have little to do with whether the law allows it or not. instead he carefully and methodically breaks down why, in this case, breaking the law is necessary. Many of the arguments he responds to are consistent with conventional or pre-conventional ethics.

i strongly recommend giving it a read for its own sake as one of the defining works of morally couched political philosophy from the last 100 years. https://www.csuchico.edu/iege/_assets/documents/susi-letter-from-birmingham-jail.pdf
