*Facepalm*
I don't understand why this is a question. It's like asking why Scar killed Mufasa. It's bleeding obvious.

Zira was evil, duh

[WildSimba]

What if Zira didn't actually want to kill Kiara? WHAT IF SHE JUST ACCIDENTALLY PUSHED HER OFF A CLIFF.

[VitaniFan]

She wanted to attack SIMBA but Kiara jumped in front of him and Zira tackled her instead! OMG.

[PrincessKiara]

Zira was pouncing to attack and kill Simba and Kiara intervened to save him. Then the two ended up rolling down the cliff. Zira was not doing a single thing to Kiara. She meant to do it to Simba.

[NalaKiaraTani]

Because she doesn't like Kiara
