In ME2, during Jack's loyalty mission, you hear the scientists saying that they can't let TIM know what's going on in the facility, or he would shut it down. After it's done, you find out that TIM had the surviving scientists forcibly retired (ME3 TIM would have just given them another job), and had ordered the facility shut down just before the riot.
Well, keep in mind that those video journals in Jack's loyalty mission are probably at least 8 or 10 years old. Jack was born in 2161 according to the wiki and seems to have thought of herself as still a "girl" when she escaped, so I'm thinking that means 2177-78 at the latest. So TIM probably wasn't as far down the road of megalomania and indoctrination at that point.
Contrast that with how he handles Project Overlord. He criticizes Dr. Archer's actions in his communications with Shepard, but he also implies that he disapproves if Shepard sends David to Grissom Academy. And in ME3, we find out from Dr. Archer that TIM wanted the project continued. That may be partly retrofitting on Bioware's part, but I found his "I don't condone Dr. Archer's actions" in ME2 to be kind of half-assed anyway, and there are other times (Horizon and the Collector Ship) when he clearly does not tell Shepard the whole truth.
I never found him especially trustworthy in ME2, and again, while there may be some retrofitting, it made sense to me in ME3 when we found out that he was deliberately putting forward Cerberus's most acceptable "public face" for Shepard and hiding the organization's more reprehensible elements.
