[Tron: Legacy] What, if anything, could have been different about Sam's disc to convince Clu 2.0 to not try to kill him?

Clu obviously hates users, but when the two first meet, Clu is relatively friendly until he sees Sam's disc, at which point he says he "expected more." 

I always assumed that what Clu wanted was for Sam's disc to have admin privileges like Kevin's, allowing Clu to escape, but was there anything else Clu was looking for? For example, if it turned out Sam hated Kevin as much as Clu did, do you think Clu might have tried working with Sam (a filthy user) instead?

Clu looked into Sam's past (disc) hoping to see something that was missing in his own development.  Clu probably knew about Sam from his previous conversations with Kevin, before he became overly driven to develop his 'perfect system'.  Kevin likely talked fondly of Sam and Clu looked for some reflection between his own development and Sam's.
