Hughes replaced the 64-year-old when he was dismissed as Rangers boss last season and has been linked with the vacant post at Elland Road, following Warnock's departure last week.
"I meant to say dismantled but destroyed was obviously at the back of my mind," Warnock told the Daily Star.
"I do feel a bit of bitterness towards Mark Hughes, I always will. (QPR owner) Tony [Fernandes] is a very clever man and his other businesses are superb but I think he would be the first to admit he trusted people too easily."
Leeds are 17th in the Championship, five points clear of the relegation zone.
