He's already said he's looking to rehome it, that he's not capable of taking care of it properly, plus his wife doesn't want him to have it. If fed properly, this burm has the potential to double in length and without going into that fully prepared for the consequences, it's a bad idea to keep it. He got the snake and assumed it was a ball python, not a burm. I don't think anybody on here is being negative towards burms, they're just giving OP some advice as to what to do with the snake now that he knows what it is and that he doesn't want to keep it.
Also, it's downright offensive to suggest that a BP owner would strangle a burm for 10 ball pythons. People here own snakes because they love snakes and I seriously doubt they would kill a burm just because it's a burm and not a ball.
