Both the behavior of the blond dude and the reaction of his superior officer to that behavior were ill-motivated. One doesn't get angry and violent with a special agent simply for dealing with extraordinary evil, and one doesn't knowingly draw loose cannons into sensitive missions.
The blond dude seems to think the police is supposed to be arbiter of justice and protect the peace, so he saw the scar guy as the outsider who has no right to handle this special "case". That got him killed for not heeding his superior's advice.
The superior saw the other side of the world, been living and handling the cases with the special agents.
He thinks that the blonde dude could be of use to assist the special agent's work since he is so obsessed with those incidents.
Hoping the blonde dude could be the representative of the police force in the special agent frontline force.
That is the conclusion that I draw out from this chapter.
