Framing harmful practices against worse alternatives makes them seem righteous

Evidence

How lifestyle and industrial practices are viewed is colored by what they are compared against.

If used skillfully, framing the issue by advantageous comparison can make the lesser of two evils not only socially acceptable but even morally right. — Albert Bandura, Moral Disengagement, 2657

• XREF: Contrast principle/advantageous comparison is a core moral-disengagement mechanism; this crystallizes it cleanly and would pair well with the other disengagement mechanisms already in the book.
