The problem is that they wouldn't be able to keep Kirito in the game, it's not SAO, and Kirito could just log out of the game and ask all his friends for help. And Sugo's idea of drugging Kirito with an aphrodisiac so that he can rape someone is generally stupid. I think this scene was made to show the player that Sugo, who held Asuna captive, is back in the game and to show Sinon's capabilities.
As for the fact that Kirito would become hypnotized "trap"... Well, it's a risky move. In the game
God's Blessing on This Cursed Ring! everything was fine, but when Kazuma himself got fucked, the fans weren't very happy and the game lost some of its audience. It's a matter of taste. But don't give up hope, perhaps Inoda will personally humiliate Kirito in the end, in front of Asuna.
