Why do so few major characters actually Die to infected in The Last of Us?

I’ve been replaying both The Last of Us and Part II recently and realized something curious: almost no significant character actually dies during a direct fight with the infected. Sure, we see characters get bitten—sometimes even off-screen—and discover they’re doomed afterward, but it’s rare to witness someone getting overwhelmed mid-battle by a Clicker or a Bloater or even a runner and die brutally on the spot.

I find this really interesting, because the infected are obviously a constant threat, shaping the entire world and forcing everyone to be on guard 24/7. Narratively, they’re the driving force of all the world's destruction. Yet, when it comes to big on-screen moments, so much of the lethal conflict ends up happening between human factions instead.
