Problem the script removes KOs, it's supposed to move both KOs + WOs on a tie?

In this script, the players link to eachother after they both die. If a player dies, it's supposed to give then 1 WO and the killer 1 KO. If the player wins they get 1 KO and the killed gets 1 WO. If they both die, it was supposed to not count it at all. But the problem is it just gives them both 1 WO. I don't want it to give them anything. How do I fix that? Keep in mind it already removed the 1 KO.

Near line 33 was edit 1. Near line 70 was edit 2.
