who sunk the bismark? Hitler did, Göering did, Admiral Lujthens did, her own crew and the brit sailors.
Hitler: he sent the ship in a suicidal mision alone, even the most powerfull battleship (the Bismarck untill the Yamato was finished) could not resist the attacks of all brit home fleet. also, her strengh was the range of her guns, staying far away landing 380mm shells in the enemy.
Göering: the Luftwaffe could have protected the Bismarck, at least a bit, both Lujthens and Lindemann died waiting for the luftwaffe to apear and save the day.
Adml Lujthens: he ordered KsZ Lindemann not to return to port, so the ship went into the atlantic after sinking the HMS Hood and severely dmging the HMS Prince of Wales. so, they where hunted by all the home fleet.
the brit sailors: brave man, fighting for theyr country, the distroyed rudder was a lucky shot and made the Bismarck an almost static artillery base so, they caused the sinking.
her crew: they scuttled the ship.

so, the ship was doomed by the actions of both the brit navy and the Reich. you cant say "he sunk the ship" because the ship sunk as the combination of all those factors.
it depends on how you see the fact.
ps: the way i see it, the crew scuttled the ship.
