Are you going to meet Buddha on the road? Bloody unlikely. You meet Satan all the fuckin' time.
Kill the shit out of him.
We all have a bit of the Satan egregore following us around. Your job: commit unlimited violence upon it.
If you meet Satan on the road, take the war crimes list as suggestions. Blind him with lasers, pelt him with flechettes, and then shove him onto land mines. Stab him fifty times, rip out his guts, and take a shit in the resulting cavity. Blast the area with chemical, biological, and nuclear weapons. Salt the earth. If there's anything left of the body, bust out the napalm.
The rack? Iron maiden? Apple of anguish? All things Satan richly earned, and more. Twisted desires are not twisted as applied to Satan, with the exception that he should be considered a biohazard and never touched directly. Use gloves. A mask wouldn't go amiss.
If he surrenders, shoot him again. Twice. It's fine to start at the feet and work your way up.
If you have violent urges, hunt down a Satanist and beat the shit out of him. The violent urges exist for a reason; your job is merely to allow them to find their proper place. It is your privilege and your duty; feel not guilt for being violent, but feel guilt for suffering a Satanist to live.
Of course, take care of yourself first. It's much harder to ruin a Satanist's day if you're in jail, so don't get caught. Always seem to be obeying your local laws. (They're dumb, it's not hard.)
