Khan didn't go too hard on the recruits. Hurting them wasn't the point of the lesson, and he also wanted to reassure them a bit after everything that had happened with the Tainted ape.
None of the recruits were first-level warriors, and their proficiency level was also lacking. Many failed to perform perfect executions of their martial arts even after spending an entire minute preparing for their attacks.
Khan had some hopes for the six recruits who had faced the Tainted ape, but they turned out to be too innocent to express proper killing intent. Deborah came close to attempting a deadly blow, but she got scared near the end of her technique, leading her mana to disperse before her open hand could land.
