A religious group killing others is the exact same as any other affinity group killing others. It gets no special treatment. hierarchical organizations within religion on the other hand are what that usually makes religious groups problematic in the long term.
It is fine as a voluntary choice. The problem is only really with Death cults.
Obviously if one means volountary for joining a religion, one also thinks the same for those people killing others unjusticely
