Shooting any and everyone you come across regardless of needing the "loot" they have is your standard d-bag simulator experience. This is what "ruins" games like Ark, Rust, 7D2D, etc. Sure, you might need resources and come across a victim to loot. More often than not you have players who need nothing and are bored so they just run around killinig any easy prey they can find and avoid the other dangerous players.
In many cases these d-bag simulator players focus on players that are offline and can't fight back.
In many of those games I listed, it's extremely common for new players to spawn and within minutes be killed by high levels for no reason (no loot or personal gain). If they have a PvE safe zone for the starting areas, then these new players are often killed within minutes of venturing out. Again, often for no reason.
It this game (and other similar games) don't bother to build proper PvP rule sets and gameplay they will contineut cater to the d-bags in PvP environments and force most other players into PvE private servers and creative mode. In both cases it splits the community and keeps the total player base small. Games like WoW, League of Legends, Overwatch, etc have massive player bases because they have solid rule sets that make the full experience enjoyable for everyone... not the small subset of d-bags that dedicate enough time to farm the new players and troll them till they quit.
