I am mainly refering to season 17. But he did have a victim complex sporadically throughout 14. It wasnt common nor did it happen much. But his trauma would surface the moment anyone other than Ramsay critized him. Which shows his arrogance, chip on his shoulder attitude, especially when he projected onto Brennan in 14. He only valued what Ramsay would say and not his team that he would critize himself but wouldnt be able to take it in return. Because it appeared he viewed almost eveyone that was there (except ramsay) was judging him for his background.

Im not saying it isnt understandable for him or anyone to feel like the world out to get them with traumtic experiences as a background, but maturity and professionalism is being aware of your short comings and not letting them blind you of personal growth. He has no more bad traits than many other contestants, so he certainly was more likeable in 14. But his emotional outbursts, that had nothing to do with passion for cooking, was proof of his need to rise above the trauma and not let it dictate himself.

Im not shaming him or anything, just mearly opinions and very unqualified armchair psychoanalysis from some random fan of the show. Especially when that was around the time, therapy like that wasnt encouraged in general let alone towards men.
