What's more once the fighters enter the station they move their main ships closer to the moon and away from the station making a scorched moon move even more likely to succeed.
The Imperials on the other hand are charged with trying to stop the ships from escaping the system so even then some of the Imperial ships might have survived the destruction of the moon (even so as you say BmB the Emperor didn't give a damn about friendly fire so why would one of his minions?).
Try reading next time. I said they do care about friendly fire since moving where the death star might hit a friendly is effective.
