In general, people take action out of personal reasons, the urge to revenge, or reasons of economic profit but always having connections with the people they are taking action against or pro. Yet, there care cases when people have no personal reasons when taking an action. This means that they take action only out of profitability, they are lured by the extreme amounts of money they will get when they finish the action. For instance, the hit men kill not because they hate, or have personal business with the person they kill, but because they work as mercenaries for someone who will pay them grossly when finishing the business. In the end of the day, this is what mercenaries do.
