If you choose not to give the Parents credit, then there wouldn't exist Interea or Khemia or even Adastra 2. Replay Adastra towards the end, and see what happens when you deny them.
Might seem like a bad choice and Thay they are not trustful, but I believe they are there to help, even though their methods are questionable
Seems to me more they get involved the more pain is caused
For them of course, but the alternative is definitely not better :(
