Second, the reason I take issue with talking deathclaws is it’s the same reason I hate zombie genre pieces where… after the protagonists have killed hundreds of zombies in gruesome ways… the zombie franchise creators then go to imply that zombies have feelings, are intelligent, can be cured, etc. This isn’t a bad idea by itself. The issue is that if you want the player to feel like complete shit for having killed hundreds of creatures that you might have had the potential to save and evolve, then I probably don’t want to play any game you design because you and I are miles apart on what “letting the player feel heroic” means.

If you take away that, then you’ve got one less badass monster in the wastes. That’s a minor point, though, and again, the main reason I don’t like talking deathclaws is because they have a huge potential to make you feel bad about fighting other deathclaws that were not designed to be saved.
