Narrative:
I issued traffic to atx X. There were 2 targets of concern. Y was VFR being worked by another sector at 4500. Z was unknown at 3800 mode C indicated. Pilot of the atx X elected to respond to TCASII RA from Y and descended into Z almost hitting it. Then climbed to avoid Z after the fact. When I asked the pilot why do such a thing, he responded he had to react to TCASII RA regardless what I say. This is insane at best and a blatant misuse of technology and bureaucracy and must be stopped before it gets totally out of hand.
