I just found out that babies can be deemed "unadoptable" because they've been neglected for so much of their life already.
Which makes sense, because giving them the attention they need would be foolish. I mean, what's the point of trying to raise them in a healthy fashion after they've displayed some anti-social tendencies as a result of losing their parents? They need love, and there are parents happy to give it, but they've got some bad tendencies as a result of neglect, so we'll neglect them more.
Its a flawless plan.
