"If all I can do is bring discomfort to those who have so abandoned their principles then it's a job worth doing, but I believe I have and can do much more," the TUV leader said during the party's annual conference.
The party oppose power-sharing with Sinn Féin.
Mr Allister said the continuing trial of two men accused of killing two soldiers at the Massereene Barracks in Antrim in 2009 illustrates how decommissioning was "a con".
"Here we have Provo weaponry and Provo bullets, supposedly decommissioned, but very much on active service in the murder of two soldiers. Yet, not a squeak from those who once demanded not just decommissioning, but photographic evidence.
"Well, here - not for the first time - we have indisputable forensic evidence that it was a con and, suddenly, it doesn't matter. Why, because preserving Provos, and thus themselves, in government is more important than the truth," said Mr Allister.
The TUV leader also referred to the recent challenge over the proposed removal of the crown symbol from Prison Service uniforms, saying a "supposedly irrelevant MLA, to whom they say no one listens, unearthed the machinations that were afoot, that the DUP woke up... TUV set the agenda this week".
He also called for the SDLP and the UUP to form an opposition and not act as "fodder for" the DUP and Sinn Féin, "who when it suits uses them and when it suits abuses them".
"How long can they put up with the humiliation to which they are subjected?" He asked.
Mr Allister also described current politicians as "self-servers who will pay any price to cling to office, any office, even that with those who butchered our kith and kin".
The former DUP member said he had "special advisers in surprising places" and would act as a catalyst for change at Stormont.
"This one-man band has shown the stir just one can sustain. Think what a whole orchestra of opposition could do," he told party delegates.
