Warren Vidic
The lead scientist in the research of Altair. He is the a scientist (the exact position is not clear) of Abstergo Industries. He is shown to be somewhat of a ruthless man. He can also be seen as fair, as he "allows" Desmond access to his emails when Desmond pickpockets him. (This is presumptuous. Vidic was was set up as something of a clumsy man. Through numerous emails he is constantly asking for passwords that he has forgotten, or he is thanking Lucy for returning his key pen to him. The fact that it is stolen from him could simply be him being the unaware cluts that he is shown as. It is possible again, that with all the cameras, that Vidic is in fact letting him out. As Vidic vouched for Lucy who's an Assassin, maybe he supports them as well).
He did not admonish Desmond even after his cryptic reply to Desmond's questions: "I think you know enough already." Desmond demands an explanation and Vidic offers "You know what I mean." This leads to the insinuation that he knows Desmond is viewing his emails, but does not retaliate harshly because he believes you have the right to know what is going on, to some extent at least. Initially, he attempts to push Desmond beyond his limits by keeping him in the Animus, only to be accosted by Lucy. Relenting slightly after Lucy's initial concerns, he is further pacified after Desmond agrees to not resist their work. He remains pushy throughout the game, chastising Desmond for wasting time at the Animus memory selection screen for delays or for walking around the room in the middle of a memory segment.
Emails accessible after the completion of a memory segment further show him to be impatient, perhaps to the point of being sloppy. His emails are written without capitalization, and he doesn't bother signing his emails. He wonders aloud to Lucy why she bothers signing hers, since it indicates the sender quite clearly in the header. On at least one occasion he loses his access badge, which Lucy finds and returns for him. He is dismissive of her calls for him to be more careful with it, replying that she should be more focused on the Animus and their work with Desmond.
