Couldn't you instead simply provide emotional and community support to that vulnerable person, to help them get back on their feet and live their own life, and let them come to your faith naturally? I feel like conversion would be superfluous when it's just about helping people, and when it's targeting vulnerable people the potential of it turning predatory seems fairly high.
Often times high control groups use their indoctrination as emotional and community support. They use their beliefs to provide the person with hope, love bomb them, spend a whole lot of time with them and make them a part of something "greater". So they become predatory through the support, as they aren't doing this without any benefit to themselves. It is as if emotional and community support has to be separated from religion and ideology in order for it not to be predatory.
