[X] Destroy Them
There are exactly two concerns that would make me postpone it.
1) Forewarned is forearmed. I'd like to have assurances that we at least know enough about what those artifacts actually did, and more importantly, how to counteract them. In case we meet something like that in the future.
2) Sorting algorithm of evilness. Evil, corruptive and subversive items must end. On the other hand, keeping some of the merely horribly destructive items might have merit, if only as a study subject.
Under no circumstances must Uni learn we destroyed all this before she ever got a look.
