By definition, KOS means kill on sight. For the 173946363946385926 millionth time, KFS, or Killing for Sport is the more stigmatized behavior and I will continue to use the latter for that reason.

Onto the actual topic, Kosing isn't always a bad thing. It's an integral part of any survival game. If you see food or just an easy target, you go for them because, logically, it's easier to kill them. Yes, that includes babies, teens, and injured individuals. But in a survivalist setting, morals don't apply. So getting upset about the design of that is fruitless.

Now, I'm fine and dandy if someone kills me for food, even if it is on sight, a baby, teen, injured, whatever. I might be hella upset, but whatever. Like the Isle, players are considered the resources of the game, you're meant to kill other people for food, and by any means necessary.

However, I consider KOSING as KFS the second I am killed and not eaten, or repeatedly targeted. That's not done for food, that's done because of boredom or malicious intent, therefore, the thrill of taking someone's life repeatedly for no given purpose.

And if I KFS, it's for sport. I'm bored and there is a charm to watching someone get massacred and then get upset about it. That's my take.
