〜べくしてV（た）

Meaning

Means "there was an inevitability for it to turn out so, and it naturally turned out so." It states that it was not by chance, but a natural consequence in which the conditions that ought to occur had come together. The same verb is repeated; the basic forms are 「なるべくしてなった」「起こるべくして起こった」. This is a different usage from the 「べく」 that expresses purpose or volition (〜するために).

Examples

あのチームは、勝つべくして勝った。 That team won as it was bound to.
油断が続いていた。事故は起こるべくして起こったのだ。 The carelessness had continued. The accident happened just as it was bound to.
彼の成功は、なるべくしてなった結果だ。 His success is a result that was bound to come about.
