"I don't remember reading that in the codex"

What we can tell from observation, is that all indoctrinated subjects are compelled to Help the Reapers due to a brainwashed mind set. The Reapers got the Hanar to think the Protheans want him to side with the Reapers. Rana thought the Asari would "ascend". Saren thought he was going to save everybody. TIM thought he was saving Humanity as well he thought he was advancing the Human race a trillion fold.

"which has a 66% chance of succeeding, instead of just killing him, which has a 100% chance of success."

No, indoctrination has a 100% chance of succeeding to them, but they ignore the variables... Shepard is an anomaly, but they believe that Anomaly can still bend to their will. What's even funnier here, is that wanting to indoctrinate him is the explanation for why he doesn't kill him. From a literal perspective you must ignore that Harbinger is being REAAAAAAAAALLLLLLYYYYY careless by flying off. You must also ingore that Harbinger was purposely avoiding killing Shepard because your friends die based on how close you are to them. The distance between Shepard and his squad mates in that cutscene decides whether or not harbinger sucessfuly kills them. Which means he is being careful not to kill Shepard himself.
