Kant, Nietzsche and the idealization of friendship into nihilism

Is friendship still possible under nihilistic conditions? Kant and Nietzsche are important stages in the history of the idealization of friendship, which leads inevitably to the problem of nihilism. Nietzsche himself claims on the one hand that only something like friendship can save us in our nihilistic condition, but on the other hand that precisely friendship has been unmasked and become impossible by these very conditions. It seems we are struck in the nihilistic paradox of not being allowed to believe in the possibility of what we cannot do without. Literary imagination since the 19th century seems to make us even more skeptical. Maybe Beckett provides an illustration of a way out that fits well to Nietzsche's claim that only "the most moderate, those who do not require any extreme articles of faith" will be able to cope with nihilism.
