I would say it's possible that one of the gas giants have destroyed one or more moons. Because of their size, their gravitational field is much stronger than the smaller planets. That means smaller astronomical objects could have been pulled into their orbits. Some scientists are even thinking that Jupiter might have destroyed some of the early planets when the solar system had just formed. So, yes, I would say it's possible that Jupiter had a history of destroying moons when it was young. I hope that answers your question. Have a nice day!
