Virtually every adult killed by snakes in America was asking for it. Rattlesnakes sure as shit know they can't eat humans and would never attempt it. They are named for the mechanism they use to scare us away and bite when that fails. A huge number of rattlesnake bites are to the face or hands because it happens when some moron ignores the rattle and picks up the snake.
Wolves, unlike rattlesnakes do sometimes deliberately attack humans with 'malicious' intent. Rattlesnakes never do.
