I dont think Queen is a double edged sword. He only performed idiotically against Sanji for his own motives. In a normal fight he wont be spaming lazers waiting for his opponents to bring out a RS. He’ll be plaguing them.
As of now…Queen beat Drake, O-Lin, 2v1 beat Marco, Chopper, and wouldve killed everyone in the Live Performance floor. I dont think thats being a double edged sword. I think thats doing more than the YC1 counterpart did
Queen turned thousands of his own crew against them leading to their defeat, thats why many of us view him as a double-edged sword.
If he was serious then the BP would hve won the war by now but because of his childish personality they will lose, all because of what he did.
If only he stayed focused and didn't do anything rash, he should have used the mummy bullets, and not say stupid things to his own crew, and should have not played around with Chopper leading to him creating the antidote, and should have focused on his opponent Sanji.
Queen killed a lot of the enemy but also turned even more people against them
