If she's willing to work on things and try to come to an understanding that anything with teeth (dog, snake, ankle-biting-toddlers, etc.) has the potential to bite and can get past her fear, great. If not and the snake is going to suffer in terms of it's care because she's scared/no longer enjoys it/doesn't want it/ is "over it/ whatever, then absolutely take it off her hands for her and more importantly for the sake of the animal itself. If it would make you feel better to offer her something, by all means but if she's set on getting rid of it and that's that, then you just lucked out big time and should go play the lottery, lol! You didn't create the situation or the circumstances and I admire and applaud your honorable intentions of wanting to be fair in terms of the potential monetary value of the animal. That's on her to either figure it out and accept that any animal can bite or to make other arrangements for the care and housing of the animal she previously committed to raising/providing for, regardless of whether or not she recoups her money or not.
