Why did Kristatos not want blood in the water if his intention was to kill Bond and Melina?

think he wanted the fun of dragging them about for a time as blood spilling in at the start would attract the sharks too soon and it would all be finished quickly

Showing blood and gore would get the film a R rating

Because he wanted to enjoy dragging them through coral for a little bit, if the sharks ate them too quickly then it wouldn’t be as fun

Because the frickin' sharks hadn't yet been fitted with the frickin' lasers!

Was that too much to ask?
