Maybe he's trying to forget the previous times, lol. Rushing snakes (when trying to handle) is rude & scary for them. It's what PREDATORS do. It's what the "bad-guys" do. He won't learn to trust you until you learn to trust him too...communicate your good intentions. No quick pick-ups!
If you want a friend, you have to act like a friend. If you're too chicken, put gloves on for a while. Or just give him something besides your hand to sniff first, something that doesn't smell like anything he'd eat, so he gets the idea that dinner has NOT arrived.
