The scope of the Scorned Wraps was very narrow. It could only be applied to a very specific action, and only if that action was being taken by the system.
By comparison, the shard was far more powerful. It superseded the system and applied to the laws of the universe itself, fundamental laws that even the system would have to abide by.
However, because of that scope, it was far more dangerous. And, because its very essence looked down on the universe from the ceiling above, just being in its presence made one feel small and vulnerable. It was the sort of treasure that could break a person.
It seemed that the Professors weren't just insane because it was their original disposition, but being in the presence of this shard for so long could leave them completely broken.
By the same token, though…
