i was thinking the same thing....
if the snake had not begun to shed, its not good to jump the gun.
whether you were able to take it off or not, if theres no sign that the snake has attempted to get it off, its probably not ready to.
Its like peeling a banana b4 its ripe....k, maybe a bad analogy, but you get my point.
Not sure of what(if any) bad things can come of doing something like that, but id imagine the skin to be a little tender as well as increasing the chance of an infection, due to the less-then-developed scales which usually shield a snake from many bacteria's
if you have your humidity up to par, it should be able to shed on its own.
in the future, i wouldn't do this again.
theres no point.
