I don't mind the control option. I had a suspicion throughout ME3 that TIM was probably onto something, so the fact that he's half-right at the end makes sense for me. I still didn't pick that option as it was a little too close to slavery for me, genocide somehow seemed fairer.
That actually shows up one of the problems with the game's auto-dialogue. My main Shep was a paragade that saved the Collector base and left Cerberus on good terms, and he would have been willing to hear TIM out on Mars if the game had let me make that choice. But no, "You're either with me or against me!" When did Shep become a Republican Space Ranger?
