It's a great question, definitely my favorite of the whole series. But the most complete, big-picture answer we have is: "they never revealed the details about Wilson's part in the Sentox conspiracy".

Graem Bauer (by personal confession) and Alan Wilson (by Tony Almeida's accusation) are guilty of the same things.

Graem Bauer: ''Yes, I gave the order for [Palmer's] assassination... and agent Tony Almeida... and agent Michelle Dessler. Your co-workers. They're all dead because of me. I arranged everything. I set the timetable. I paid off the killers. I even lured you out of hiding to take the fall. Today wasn't the first time I tried to have you killed, Jack.''

And about Alan Wilson, Tony makes these extremely vague statements: ''He was the man behind Charles Logan. He's the one who ordered the hit on David Palmer. And he had Michelle killed to cover his tracks. This is the man who murdered my wife, Jack.''

From these two quotations, Graem's and Wilson's culpability is almost identical, right? One of the few other details we are sure of is that he was above even Logan, at least at the same high level as Graem, Philip, and Anatoly Markov. But we cannot determine if Wilson was higher than Graem though. It is tempting to believe he was, though, because we didn't see him during the actual airing of Season 5. We wish we knew.
