Well, the thing is, not everyone comes back. The Sky Troopers? The Zombies vanquished? That Weed sacrifice? They didn't have the badge. They're dead. Mostly important zombies/plants have the badges, which is also why Chemist is doing what's doing, ending the war by knowing that nobody will truly "die"...but...his way is a little...twisted...

The captures aren't really "capture points", more of where the plants (or zombies) create their gardens/graveyards, where they can change everything around them. That, and just to mark where they are on the map, because the places where you capture in Turf Takeover are called Capture Points (I think)
