No, fortunately you can't justify any evil. You simply stop being good. Justification lets you off the hook. There is no justification, and more importantly this isn't consequentialism, though it seems you think it is (and that can justify any evil).

Falseness, and the teaching of false and limiting beliefs is one of the greater evils, and unlike many things its not just normative and thus can't be discounted as such because it results in actual loss at some point.

Sophie's choice is a framework, and its not made up, people have used it.

I never said that, I said choices are very few. That's putting words in my mouth, and we're done.
