The reason it might seem this way is because as it stands now, you gain more from killing a person than not killing them. The way to remedy this fairly, without breaking the current system, is to inflict some sort of penalty on a bandit. For example: If you kill a survivor, you are more likely to attract zombies from farther away. Requiring more stealth than usual if you plan to continue. The more you kill, the harder the game becomes for said player. It won't mess with people who tend to kill for killing, or kill for the loot since they have to decide early on. Does killing them merit me having a tougher time moving around? If so, go for it. But at a price. So what this would do is give a simple decision on all players. Don't kill survivors and not take their loot. Or kill and take the loot, but make the game harder. That's what the game needs atm.
