The furious reaction from the IAS officer came after some news channels aired Faesal's photograph alongside images of Wani's bullet-ridden corpse.
"By juxtaposing my photos with the images of a slain militant commander, a section of national media has once again fallen back upon its conventional savagery that cashes on falsehoods, divides people and creates more hatred," Faesal, the topper of the civil services exam in 2009, wrote on his Facebook page.
While Kashmir was "mourning its dead, the propaganda and provocation being dished out from red and blue newsrooms is breeding more alienation and anger in Kashmir than what (the) Indian state can manage," he said in his Facebook post.
Faesal threatened to resign "sooner or later" if the "nonsense" continued.
"Personal vulnerability apart, the very fact of becoming a part of a ridiculous debate is something which has disturbed me very much. Have I joined IAS to do a job or to become a part of your sadistic propaganda machine?" he asked.
"In fact when I qualified this exam I never thought of spending my whole life scratching the desk and if this nonsense around me continues, I might prefer to resign sooner than later," he added.
Wani was killed on July 8 and his death triggered a wave of violence in the Valley that has left more than 38 people dead in street clashes between protesters and security forces.
