Null was just a rank user once upon a time that, somehow, inherited the kingdom just like King Bran.
He's been hesitant to punish the very few users that remain from that era, as they are literally his senior here.
Also, he was much more social and involved back then.
Right now he's like an old geezer whose friends are all dead and who distrusts/dislikes all those god darmn young'uns who run in front of his lawn and wear those outrageous clothes, and he ain't no attaching himself emotionally to any of them since it's pointless anyway because he might croak soon.
Having your friends die is tough, but having to kill the remaining ones must be tougher.
Also, he has to deal with
@AgendaPoster and his friends shooting at bottles with slingshots. It's pretty much the neighbourhood descending into unruly delinquency.
