Venomous it doesn't matter. Pick it up and use it as you see fit. Nonvenomous snakes are illegal to kill in GA. Think for a second about a bald eagle. If you get caught with a feather you're facing jail time. I'm guessing snakes would fall into the same category. Also in GA it's legal to pick up roadkill so picking up a rattle snake would be no problem. I would poke it with a stick first and then make sure it's head has been cut off after verifying it was dead.
