Sometimes that Circle is where you need it to be. It's about zone control, not necessarily kills.

Karthus dies under their tower, throws up his circle, wall and spams his Q. His team should be able to take the tower and skitter off. Engaging them risks sitting in Karthus's cicle of death and taking additional damage from the wall reduction. It's not a tactic that should be constantly deployed, however, if it is done right, Karthus does serious damage to the enemy without actually sacking kills, so his gold value goes down.
