batirse en duelo
From LSJ
μὴ φῦναι τὸν ἅπαντα νικᾷ λόγον → not to be born is, past all prizing, best | not to be born excels the whole account | not to be born exceeds every possible estimate | not to be born is, beyond all estimation, best | never to have lived is best | not to be born is best of all
