Depends on what type of rattlesnake it is Noone should ever take an animal if it is in low population in the area...and I never kill anything that I don't plan on eating...that is one of the rules of the jungle I have eatten alligator and frog a bunch of times...i prefer alligator over frog though...just never had the opportunity to eat rattlesnake (or turtle soup, although it is commonly eatten by my fellow swamp people)....and I would have no idea of how to cook rattlesnake if I wanted to try.....but given the opportunity, I would give it a try.
