Justifying the murder of someone by dehumanizing them is exactly what the nazis did. It’s what Israel is doing in Gaza, etc., calling everyone Hamas and dehumanizing them. Nazis may be terrible people who need to be fought against and whose ideology needs to be stopped, but it’s never good to start dehumanizing groups of people over any criteria. All that said I love playing Wolfenstein and Indiana Jones games and killing hordes of nazis.
They should just swap their Jesus out for the one from the game The Inquisitor. That would be way cooler, I’d even consider going back to the church.
