Sevastian isn't Tybalt. He can make things far, far worse than Tybalt could.
I'd like to see what he can do.
Malus or Fulco refusing the duel would be tantamount to admitting treachery and dishonour upon their houses. It's too public a matter to be refused without great shame.
I remember Pianese, Capets, Vesperians, Tybalt, Jeffrey and others saying the exact same thing. And Sevastian laughing at some of them.
