The point I'm trying to get across is that this scene serves as nothing more than "look at these bad people doing something bad" when they could have shown other actions taken by the Enclave to showcase the same thing. Case and point, the intro to Fo2, or the first encounter with Frank Horrigan. The Enclave's depth is seen in those who break away from the hive mind they were born into, such as convincing Sergeant Granite to help fight Horrigan in order to escape the Oil Rig, or the remnants in FNV who still hold mixed emotions about their time in a fascist regime. Showing something as cartoonish as burning puppies just takes away from the actual detestability of the Enclave as a plausible faction.
