Wilson was set up. He didn't betray anyone. There is no evidence whatsoever pointing at him. Only Miranda's word after he's too dead to object.
While it is true that insufficient evidence exists to prove his guilt, there is also not sufficient evidence to prove his innocence. Based on his logs we know he felt underpaid and underappreciated. According to Jacob (the guy in charge of security), Wilson shouldn't have access to the systems he claimed he went to try and fix. Wilson has a minor wound in a room I recall being devoid of mechs until after you arrive. Had he been wounded by the ones in the room prior, why did they not finish him off? He is impatient to leave, and becomes even more so when you mention speaking to Miranda (who he insists is dead already). In the moment before he dies, he seems shocked and frightened upon seeing Miranda alive.
Then there is the issue of Cerberus seeming to retake the facility. If you have the Blood Dragon Armor, the email from TiM mentions that the armor was on the facility for you and lost during the attack. However, it was recovered upon the retaking of the facility and has been sent to you. Perhaps this is just an elaborate cover up, but it seems rather odd to lie about something when there is clearly no need.
In past project cleanings, they tend to abandon the facility and those involved. Why would they only cleanse the workers this time (and based on the damage done to the facility, why bother retaking it at all)? If the attack were planned by Cerberus, wouldn't Miranda and TiM have removed all vital info/equipment/etc prior to risking damage or permanent loss due to the chaos? If it was just a test for Shepard, then why did Miranda not seem satisfied with a test she supposedly created (she is only convinced to stop questioning and likely physical tests that would come later by Jacob)? I don't see her as the type to run a test she created unless she has absolute faith in its ability to measure what she intends it to measure.
While I certainly see TiM and Miranda as capable of such actions, I simply don't see the signs here that there was enough motive on their part. Though, I do feel the intention of the event is to reinforce distrust in the player (or create some in new players). I feel that is likely why we are never given solid evidence (which it is possible Miranda actually has) proving Wilson's guilt or innocence. Miranda killing Wilson also serves as a way to demonstrate all that is Cerberus. They are cold, ruthless, and will go to whatever lengths are required to obtain their goals.
