Final Purification.

This is something that has been bugging me for sometime now and I want to share with you and get some feedback on what I saw in April, the end of winter. It was around 3-4 pm and I was on my way home from what may have been the last time I could gather supplies before the Z's "defrost" after winter. As usual my H&K strapped to my back and my Browning high power on my thigh. I passed a small catholic (I think) church and heard crying. I drew my side arm and entered the church and to my surprise I interrupted a service of some kind and thought, what the heck, a bit of God right now couldn't harm anybody, right? Wrong. It was about five minutes into the service when I saw the priest draw a gun and shoot a child in the head. I immediately drew my Browning and took sight at the priest and told him to drop his weapon, which he did so. An older man in the pew stood and approached me asking me to lower my weapon and he could explain everything. I told him to speak but I didn't dare take my aim off of him. What I am about to tell you bothered me so much I couldn't sleep for about 3 days. The boy that was "executed" was infected and his loved ones weren’t strong enough to relieve him from the horrors that he was about to face. The church had adopted a "service" (if that’s what you can call it) from Russian Army Chaplains during their fight with Zs, known as The Final Purification. Whereby, priests become shepards of God to releasing "trapped souls" from infected bodies. Now I understand the whole Suicide is a sin issue and people not being able to "off" their infected loved ones. But it still bothers me and I feel that I must do something. What do you think?
