Elena did not want to just go around destroying any monsters that she came across. Doing so was definitely a way to free some work for Kaya but if he did that most of the adventurers who came to the city in order to hunt monsters in this session would not be able to earn much and that might cause some future trouble for the guild. There was a slight possibility that those adventurers might not come back to this city for the next monster hunting session.
So what Elena was going to do was to take care of the strong monsters that regular adventurers would not be able to handle. This way she would be able to lessen the amount of dead adventurers. Most of the adventurers who died during these missions died because they suddenly encountered a monster that was beyond their league. So if Elena took care of those monsters, many more adventurers would not prematurely lose their lives and would be able to handle the weaker monsters faster.
