I have objects A and B and a join-table C.
A and B have a set of C.
If I add cascade delete to these sets, will the relation be deleted or the object related to?

When you set cascade="delete" you're going to delete the objects C, if no other object is holding a reference to C, but in your case A and B are both holding a reference to C so if you try to delete an object C from A and B is referencing that object C a exception will be thrown.
