This is to remind the viewer that the Lion King is a work of fiction, as in real life, bootlickers will keep licking even as their skull is stomped in by that selfsame boot.
The lion king, is about an oppressive regime and their "in group" that live in the pride lands.
The hyenas are an oppressed underclass that is easily radicalized by the promise of power over their oppressors. The whole situation could have been avoided easily, simply by Mufassa raising up the hyenas to equality with the rest of the animals.
The hyenas clearly had enough power to topple the pride lands, since they did it.
This video fits pretty well don't be a sucker. America once knew better. Imho we should call the people who vote and support him suckers. Because this is exactly what they are.
