The message of traditional textbooks on quantum mechanics may be read as a declaration of necessity of avoiding the non-unitarity of the evolution in time by all means including even the acceptance of a non-locality of the interactions. This immediately reminds us about the Homer's story about the six-headed monster Scylla which, together with the all-destroying whirlpool of Charybdis controlled the pass through the Strait of Messina. No surprise that in the mythology of old Greeks the fabulous Odysseus followed the advice by Kirke and that, in order to avoid the deadly Charybdis, he rather sacrificed six of his men to Scylla while saving the rest. In this sense, the "acceptable evil" of Scylla finds its traditional quantum analogue in non-locality. The "Charybdis" of non-unitarity was perceived much more deadly a danger.
