Professors in moral wankology be like

"I am repeating myself because the notion that the least evil option available is the best one, that the lesser evil if you will is preferable to the more evil one, is axiomatic, that is, it's a basis one takes when constructing a moral framework, not a consequence of one that can be reasoned through. If you do not agree with someone's moral axioms, then there is simply nothing to debate, you and they are simply operating under mutually incompatible definitions for what is and is not the right thing to do. Restating that in a slightly different way is a way of testing if the axioms we are operating under are truly different, in which case further argument is pointless, or if we merely misunderstood eachother the first time around."
