If you're wondering why it's shoot Maelstrom on sight, watch this video and read the description.

These guys take people off the street and turn them into pyschos like this guy here. They kill kids. They are up there with the scavs. It's shoot on site every time.

This unique interaction (that I've gotten) is related to: Main mission; The Pick (indirectly). Cyberpsycho: where bodies hit the floor. The side missions with the monks. Second Conflict (indrectly). And Gig: Rite of Passage.
