Ali had no intention to get subordinates yet, especially now when Prince was already half dead, and he needed to be healed first before being of any use. He could use his villain points for healing him, but why waste them. Plus after finishing his quest Prince's life is in his hands, and isn't killing subordinates, also a villain move - 'I might even get more points for killing him.' Ali thought and nodded his head in approval.
(This idiot is too scared) That's what the system thought when he heard Ali's thoughts. After all, in system's eyes these were all tricks and lies Ali told himself, cause he didn't want to get another betrayal from anyone close to him. Yet the system didn't care. There are too many minions and villains out there, who can be recruited easily. If one Prince is dead, no one cares.
