Hard to feel anything after most of that cultist's mortal shell is vaporized and what little is left is scattered to the four winds!
But I suspect these appeasing little snowflakes are asked to empathize with the Satanist's up to the point of detonation...God forbid they be asked to consider what the innocents (or their loved ones and friends!) around this demonic filth feel as they are slain by the evil bastards!!!
