Kali's death does matter, because she killed Erica and had a hand in Boyd's death.

Harris' death doesn't really matter because Harris' main goal was to be an annoyance to Stiles, and even that was toned down a lot because he died in an early episode. He was an overshadowed character in all 3 seasons, while Kali was a highly advertised villain.

I'm not saying that Kali should've lived. But it could have been Kali or Jennifer who had to die, not both.
