I think it's entirely possible that some snakes are just lil buttheads. My little male is just a biter, he's not dehydrated or underfed at all, and his husbandry is always correct. He doesn't seem stressed at all, I've never seen him roaming, only curled up and content in either one of his hides or under a plant in his tub. Yet every time you even look at him sideways he strikes, so far he's actually connected on both me and my gf. Not surprisingly though he is the only one of the babies that actually struck and wrapped a f/t meal off the tongs, all of the more mellow babies have to have a meal left outside their hides and they take them.

I'm gonna work with him slowly and hopefully he gets over it, but I still feel its possible he'll never be a very pleasant one to handle, so I think it just depends on the snake in some cases.
