Not a lot is known about the formation of globular clusters let alone their eventual outcome. It is thought however that they are the oldest objects in the Galaxy. If they were going to self-destruct, they probably would have done so long ago.
"Core collapse" for globulars is not to be interpreted as the same type of event as the core collapse of a star, which might produce a neutron star or black hole. In any event, core collapse does not signal the end of the cluster.
With globular clusters, core collapse simply means that more stars, and perhaps more massive ones, congregate at the clusters centre. Some collisions may occur but the cluster remains basically intact. Overall, the stars are essentially in equilibrium, attracted to each other gravitationally in many directions.
Just as our Galaxy of stars does not collapse because of its rotation,
I stand by my original view that the overall cluster is in equilibrium also due to its rotation.
