Player killing, sometimes referred to as "PK" is NOT allowed on JediMUD.  If you find a method by which you can kill other players here and use it, you will be immediately frozen, no questions asked. 
Historically, player killing was allowed in the Arena, which was installed near the Temple from 1993-1995.  A few players figured out ways to play unfairly (using player names like "a") and the zone was removed.
