I have an idea for GTAVI: Use the Legend of Zelda, cucco method.
Basically, the player could kill a sex worker after paying her and get away, maybe once or twice. Then, on the 3rd offence, dozens of heavily armed sex workers attack from every direction hunting down the player character. They never stop attacking until the player is dead. From then on, every sex worker treats the player with suspicious hostility, refusing to "do business", even pulling out the biggest most powerful gun the game has to offer with which to kill the player and steal every dollar the player is carrying.
Get to work Rockstar.
