They Were Holding You Back

"The Alpha: Scott, I think you're getting the wrong impression of us. We really just want to help you reach your full potential. Scot: By killing my friends? The Alpha: Sometimes the people closest to you... can be the ones holding you back the most. Scot: If they're holding me back from becoming a psychotic nutjob like you? I'm okay with that."

- Teen Wolf episode 10.

Alice is a very fortunate woman, she's the best at her profession in the world, has a group of supportive friends and a loving family. True, she probably longs for adventure and excitement or wider recognition, but that's a minor concern compared to the bliss that is her life. Bob knows of her skills and sorely needs them, so he makes a generous offer for her to join him and help in his (potentially evil) goals, sweetening the deal with the promise acclaim, power and wealth. Of course, she'll refuse because she's happy where she is. In fact, she probably quit Bob's team not long ago precisely to get that happy family life.

So how does Bob get her into the fold? He kills these happy people to remove all her links to mundane life. Usually he's smart enough to frame one of his enemies, or at least make it seem like an accident, that way he can channel Alice's rage and despair towards his cause. If Bob is especially malicious and grand in scope, he may even give Alice a Doomed Hometown and make her Conveniently an Orphan.

You can expect the fireworks to start once the secret is revealed. Alternately, Bob might instead kidnap one or all of her friends and family in order to more directly control her, or as a backup since their murder can will backfire. If Charlie wanted to make Alice pull a Mook Face Turn / Heel Face Turn (or at least leave/betray Bob) revealing this Villainous Demotivator is sure to work.

A more sinister variation happens when Bob is a Poisonous Friend who wants to "help" Alice by killing her Living Emotional Crutch and Morality Chain. The reason? "They were holding you back from achieving your true potential."

 * In the early issues of the new Batman and Robin series, Damian Wayne's mother Talia put control devices in his spine and manipulated his body in order to have him kill Batman (Dick Grayson). Her reasoning was that Dick was holding Damian back by making him Robin, though it was clearly more along the lines of unhappiness that Damian was not obeying her since when using the machine she even commented that "this is what it's like to have a son who does what I want." Damian refused her "help" after Dick freed him from the control, and his mother has since cut ties with him via Cloning Blues now that he's siding with his father's legacy.

Either that, or find children they want to acquire, remove their parents making it look like an accident, then ride in on a white horse when bureaucrats "for some reason" deny custody to other relatives. Good news is that well intentioned extremists prefer "humane" methods of making people vanish: interspacial travel in the setting is anisotropic, so even if exiles know anything of this fringe discipline and somehow can make proper equipment in the world where they were dumped, good luck with finding a way back.
