There was only one person who offered to work together with him. It was the crazy cat girl. The fact that she did such a thing in front of everyone showed just how crazy she was.
The smart people were either trying to intimidate him publicly for clout, pretend to warn him with good intentions not to go too far so that he won't kill them, or declare that they would defeat him to garner support from the spectators.
