Today you are a priest who makes money for your church and affiliated orphanage by being an assassin for hire. You got into the line of work a long time ago, back when it looked like the city was going to shut your church down (cities do that!) and all the orphans in your orphanage would be thrown into child protection programs and the foster care system. You had to do something!
"So I did what I promised myself I'd never do," you tell the Archbishop. "I followed in the footsteps of my father."
Your father was a special ops asset during the cold war, and he was the best there was.
"I only take jobs where I can be sure the target is a sinner, through and through, one who is beyond redemption."
"No sinner is beyond redemption," the Archbishop says. "You're assuming the role of God in your killings."
"Only by assuming the role of God can I get the money to continue doing God's work," you tell the Archbishop. "If it weren't for my contract killings, my church would be no more."
"Fine," the Archbishop says. "If you insist on lying to yourself, do what you have to do."
You raise your pistol and fire two rounds into the Archbishop's chest, and a third round into his forehead. You'd better head downtown to report the job done. No longer will your city have an Archbishop who uses his frock to shield a network of drug running, human trafficking, and arms dealing.
And most importantly, the orphanage is saved!
Happy Assassin Priest Day!
