I don't like the idea of having to PK over player interactions even if it somehow is a public execution though I would consider PK-ing way more over that. But once you invest 1 year with 1 char, struggle to find MA's and achieve FA's and earn TA's for things that feel rather gatekept, would you be prone to PK with ease? Personally I wouldnt and its a gigantic factor.
Chars with less applications Im way more prone to PK, but definetly not over bad faith banditry or fighting a player whose char is essentialy 'Doombringer, Devourer of Worlds, Harbringer of Chaos.' I have had a lot of crp interactions but rarely has any of my chars died, in fact only happened twice. My first char was bandited and killed to be 'eaten' in 2 emotes a year ago a week after I started and my second char was trapped in a building with 5 people to be killed and 'eaten' yet again 1 week after I created them. Of course I didn't PK over that. Its also the fact that crp banditry/darkspawn raids or whatnot is like 4-6 people fighting one with a very poor goal like 'eating you' which guarants that you'll die 100%. Nope, not PK-ing to that.
