It looks like --help is passed through to su. Try
$ sux '-?'
usage: sux [-m|-p|--preserve-environment]
           [--display display]
           [--no-cookies|--copy-cookies|--use-xauthority]
           [--untrusted] [--timeout x]
           [-] [username [command]]

So you would need 
$ sux root kate


As an alternative, set up sudo and run
$ sudo kate

Or for the specific case of running an editor, use sudoedit with your
chosen editor in the EDITOR environment variable e.g.
export EDITOR=kate
$ sudoedit filename


I hope this helps.
