Yes, devils are, in many ways, more horrendous than demons.
No, it's quite clear that the game is not limited to internally consistent ideas. I don't share your enthusiasm for this fact. Inconsistency itself is not what makes something cool, it isn't necessary for creativity, so there's no need for it. If you want a Demon Lord of Craft, that's fine, but don't claim that demons are all about entropy and destruction; rather, emphasize their chaotic nature and claim that they represent a wide variety of approaches to evil without centralized organization. My objection wasn't to a Demon Lord of Craft per se, it was to the inconsistency.
The examples you (and the Jester before you) gave are not really about daffodils, justice, and virtue. They're perversions of these things. And that's perfectly fine, because that works with demons. (In fact, I kinda like some of the examples the two of you give, good job.) But a perversion of justice is not justice. A perversion of virtue is not virtue. A perversion of daffodils... okay, maybe that one wasn't the best example, but the other two should make my point. The infinite layers of the Abyss shouldn't imply that there all things are possible in the Abyss - that simply doesn't follow.
Lol, and consistency is the hobgoblin of small minds... Forget it.
Mostly I just disagree with you. A spider is patient, cunning, and creative in the execution of its own ends. Its a perfectly fine model for a demon, the thing that lurks and waits and plots in the shadows, its goal absolute destruction, its tools anything, including great artifice.
Devils DON'T want to destroy you, they want to own you, to enslave you, to pervert you so that you become like them. Sure devils might easily create constructs, but a diabolic construct isn't about killing you, its about tricking you into falling into the hands the legions of Hell. It wouldn't be a horde of endlessly reproducing constructs that tear apart everything they contact and mindlessly make more of themselves. THAT is a very demonic concept.
I think your conception of demons is severely limited. They clearly DO plot and plan. You certainly are welcome to portray them as virtually mindless destruction, but it is in no way inconsistent with the 4e vision of them for a demon to be smart and even systematic and organized in a certain tactical fashion. And yes, the Abyss does spawn virtually everything possible. Albeit only in a warped and corrupted form, but there it is. The realm of Oublivae contains the ruins of every civilization that ever existed, a twisted sort of creativity.
