Do dolphins kill the same amount of people as sharks?

Killer whales are not considered dangerous to humans and do not prey on humans. There are accounts of killer whales turning on their keepers in Sea-world etc but these 'attacks' are extremely rare and the killer whale's in these instances did not attack the humans for food, more likely the attacks were due to frustration at being kept in captivity. Killer whales are quite capable of attacking and killing humans but choose not to, we are simply not on the menu. Sharks on the other hand are less fussy about which animals they prey on and if the shark is big enough and of the predatory variety then humans can be very much on the menu. Great whites, Bull sharks, Tiger sharks and Mako sharks kill between 3 and 4 people every year. When you compare this number to crocodiles who kill around 3000 people a year or tigers who kill hundreds of people a year it is quite clear that sharks have an undeserved reputation and the movie Jaws has a great deal to do with this.
