Full Idea
There are actions that we will never allow ourselves to engage in, not even as a means to the noblest end e.g., betraying a friend.
Gist of Idea
Some things we would never do, even for the highest ideals

Friedrich Nietzsche (Unpublished Notebooks 1881-82 [1882], 7[241])
A Reaction
Jean Genet made a point of betraying his friends. I wonder why Nietzsche thinks we should not betray our friends? Being Nietzsche, he will certainly have asked the question.
