"He's dead." she said, obviously disgusted. "Can't you respect that?" She'd never understand how some people had no morals, or how they could do such things to the dead.
She took one step forward, still holding the man. "If you want to play your sick games, you best find someplace else to do it. This place is under Justice League protection, and playing with dead bodies will not be allowed." maybe it was wrong to assume control. But someone had to protect the people, the dead included. This section of the city was assigned to the JLA, and so therefor Kara wouldn't be standing by to let this happen.
