This description of the psychological and societal effects on the indigenous savages seems to reflect on problems unique to a more civilized culture. Of course, it's your society and you devised it how it is, but it doesn't seem realistic. For instance, why would rape be common? I think even cavemen learned that women were easier to be around if given a little respect. And you mention insecurity and depression, but these things probably wouldn't exist in a community of that nature.

But, given your society the way it is, no, I would not help them. They will adapt on their own. I know it's been a long time and they haven't yet, but that is why I don't think it's realistic. I guess what I'm saying is I can't answer the question.
