A shark is nice to humans only when its not hungry thank you very much, Were have you seen a shark being tamed? I would like some proof, Not sure if even possible.
An aquarium is something different, They arent even fully nice, Meanwhile, In the game, You are some dude on a Raft surrounded by an aggresive shark that really wants to eat you, Its nature, Sharks are only aggresive to human depending on what type of shark it is, Or if its just hungry.
