Why Scharnhorst was unlikely to escape North Cape

Was Erich Bey a poor choice to command Scharnhorst at the Battle of the North Cape?

His decisions are debatable, but the British concentration was so strong that Scharnhorst was likely to be sunk under any commander.

The question points to Bey sending his destroyers away before the decisive encounter. Bey's choices can be questioned, but no replacement commander could reliably save the ship. The Royal Navy was concentrating too many forces and capabilities against Scharnhorst. The answer is a useful warning against turning an operational defeat into a single-person explanation.
