Female hyena kills a cub, followed up 3 days later by a male lion killing another baby (same clan)

A female hyena together with other members kills a cub from another female on H1-3 at Kruger national park.

We encountered a huge pack of hyenas with several babies and they were just socializing together and then all of a sudden one-off the female hyena kills the cub from another hyena. The remaining pack attacked the female mother who was defending her cub. Later, the emotion of the hyena was clear to see on the videos.

It all happened on H-1-3 roughly 23 k's from Satara rest camp.

Note: A few days later on the same spot a male lion killing another baby from this hyena group.
The male lion kills the hyena baby also on H1-3 23 km from Satara rest camp KNP.

We were driving on H1-3 and we found a male lion next to the road staring at hyenas. All of a sudden he decided to attack, he took the smallest hyena which did not run away and killed it.

Does anybody have thoughts on why the female killed the baby from the other female?
They were from the same clan.... I guess that the female who killed the baby was the leader of the clan as after she attacked the baby the males finished the job.
