I agree, put it down.
Although, if the kink is minor and the snake can eat and develop just fine I wouldn't put it down. Personally I wouldn't waist a bunch of time assist feeding a baby for months on end either. I don't want a snake that needs to be assist fed for the next 30 years. If a cat needed to have food forced down its' throat every day most people would let the poor thing go, same goes for a snake.
