Is liberation possible for those practicing unskillful means?

Is it possible for a person to gain liberation while simultaneously practicing unskillful means? Is it possible for a person to understand profound universal truths while simultaneously practicing unskillful means? Are skillful means in accordance with profound universal truths? Are profound universal truths in accordance with skillful means? An example of a skillful means is acknowledging the conventional truth of rebirth in cyclic existence. An example of a profound universal truth is that the Buddha was not to be regarded as a real and genuine fact as was taught to Anurādha. An example of unskillful means is the denial of conventional rebirth and the fruits of karma. An example of a profound universal falsify is to understand the Buddha as a real and genuine fact. Another example of a profound universal falsity is to believe like Yamaka that, “As I understand the Dhamma taught by the Blessed One, a bhikkhu whose taints are destroyed is annihilated and perishes with the breakup of the body and does not exist after death.” Various traditions divide the above conventions into a dichotomy. The labels that are used and the understanding of that dichotomy is different from tradition to tradition. In Theravada, I have seen the dichotomy variously described as right views of two types including, without vs with effluents, definitive vs interpretable, supramundane vs mundane, and in commentarial literature ultimate vs conventional. In Mahayana, the dichotomy is labeled in similar ways but also absolute/ultimate/universal vs conventional/relative/dependent.
