Am I to understand that someone gave you an animal to take care of free of charge and you sold it for a profit???
Do you see the moral dilemma behind that at all?
That is not something you should be proud of, or that you should have ever done. If you couldn't take care of the animal, you shouldn't have gotten it in the first place.
There are plenty of other people out there that could have been very happy and blessed with a new family pet Beardie, and you took that chance away from them for a couple of bucks.
..sigh...
You need to reevaluate your moral compass.
