Just for fun, attack the faithful by getting them all worked up about things beyond their control. Try to distract them from prayer. You do not want them to think for a moment that You-Know-Who (YKW) is in charge and that YKW hears their prayers. If they start praying, you're done for!
In brief, if you were the devil, you'd pit Catholic against Catholic.
Wake up, folks! The devil is prowling the earth like a roaring lion seeking the ruin of souls (1 Peter 5:8). Do not give him your cooperation.
