I also agree with Cyril, if she helps even one person then more will come seeking her help or to use her.
It will be never-ending cycle.
But, as Arkaunn said, if she uses her powers to create some sort of organisation or generally speaking "conditions" where such children can escape from the fate of dark guild slave then she could go for it.
Do not help people with direct aid sort of thing, help them get out of it themselves.
If the parents are too poor to rise children, then maybe there is a way to create some low-paying undemanding job for masses, like building roads or some other municipal works.
