Why would he want to set Face off? Face only prevents the use of most forms of magic, including his own.

It doesn't destroy anything and would prevent him from destroying things and his biggest joy is destroying things until they don't even have a form any longer, which he can't do without magic.

I can see him trying to kill Jellal out of pure destructiveness, but setting off Face? No way.
