HELL NO.
That is a bizarre method of protesting ANYTHING. It takes an active protester & turns him/her into an impotent pile of charcoal.
In a way it goes right along with the Watchtower Society's idiotic viewpoint of "The World". They'd point to the immolated victim & sneer or say pityingly, "If only they'd worshipped Jehovah! Then they'd still be with us, going out in service! Ah, well, maybe - maybe they'll be resurrected after Armageddon."
No way in hell/Cthulhu's world would I EVER allow those smug tw*ts to be able to say ANYTHING like that about me.
Here's what you want them to say, instead:
[Sister Gossipy Biddy] "Have you heard about ex-Brother JehovahisObsolete? He left Jehovah behind!"
[Sister Nosey] "I heard he went to college! THAT'S what happens when someone seeks success in "Satan's World"!"
[Brother Smug Head-up-his-ass] "He'll regret it, just wait and see! When Armageddon comes, he'll wish he'd remained loyal to Jehovah!"
[Sister Nosey] "Brother Disdains-Materialism saw him down at the local [insert your favorite hot car here] dealership, picking up a brand-new car! Said JehovahisObsolete looked ripped - like he's been eating a healthy diet & has been working out!"
[Brother Smug Head-up-his-ass pats his corpulent belly] "Lot of good THAT'LL do him. He'll be bird-food at Armageddon, just like the rest of them."
[Sister Gossipy Biddy] "I heard he's making $75K a year! Moved into a new home with his girlfriend, who's a "worldly" girl - a model or maybe a pole dancer...! Her name was - uhm, Topaz. That's it, Topaz! [turns to Brother Smug Head-up-his-ass] what's wrong? You look positively green around the gills...?"
{Brother Smug Head-up-his-ass clutches his chest & falls to the ground. As the ambulance arrives & they carry him off, he weakly but defiantly declares...] "No blood! Send the HLC down to the hospital asap!"
