I'm not trying to be difficult, but would you rather be an ISIS militant? Some pagan in the Amazon rainforest who cannibalizes other humans? Heck, a Baptist minister who blasphemes Mary from the pulpit?
I'm not saying this priest is in a good spot, but it seems really, really easy for me to imagine worse things. But I'm new to the true faith, so I could easily be missing things.
Being an ISIS militant or a Baptist minister would be a sideways move. No better or worse.
But actually, it could be argued that those individuals are in a better place than an apostate. They might, theoretically, be shown the truth if it were explained in the right way, and they could convert to the True Faith.
But an apostate? He has seen, accepted, and then rejected the True Faith. What is the chance of an apostate coming back to the Faith? Very slim. Slimmer than a convert converting to the Faith for the first time.
A first-time convert can take refuge in, "I didn't know! I had no idea! I was deceived!" ...but an apostate? They could only beat up themselves. That's something few are capable of.
