Previously, when Onyx did an investigation on NEXUS, it was clear that they usually had fatalities. This implied, they were always involved in dangers, and sometimes, some members would end up being killed.
This indicated that the dangers that they faced were not simple at all. It was impossible for them to die just by facing normal people.
Yes, at the moment, the technology involving the mutants was not advanced. And as a result, the abilities that the mutants could awaken was random, and more than that, they might not be powerful at all.
For example, if someone awakened an ability to be able to produce flames. That person, if the flames that they could produce was only the size of the flame produced by a lighter, what kind of danger could that even pose?
And, despite the mutant having the ability of generating the flame, how could they defend against a bullet? So of course, if they were caught off guard, they would die.
