Sorry if it sounds a little dumb, but as i see things.
PKs shoots everyone on sight and defend themselves
APKs shoots PKs on sight and defend themselves
Neutrals doesn't shoot on sight but defend themselves
Ghandies doesn't shoot and don't even defend themselves
PK need someone to shoot at. (or get bored)
APK need PK to shoot at. (or get bored and useless)
neutral need peace. (or can't do their business)
Ghandies need to change their mind. (or get killed by PK)
So the first two group, at least, need pvp, need some fights.
So, APK are not ghandies.
All the 4 groups are able to troll.
WWP gathers APK, neutrals and ghandies.
So, it never simple.
