Narrative:

A VFR aircraft was being vectored away from departure path of air carrier X. VFR Y altitude 6500. Traffic issue to air carrier X. Air carrier X turned away from Y -- at 6500 and told to climb to 14000 unrestr. Air carrier X received RA to descend and was observed leveling at 5800 ft. Air carrier X was in a 6000 ft MVA. X had to maintain own terrain clearance for continued climb. Y was 2 mi away from air carrier X. All actions were not necessary and RA in my opinion put X in an unsafe proximity to terrain.
