But what if it's a more personal angle?
We don't get to see Klaus' wife, Stacey's mother, mentioned a lot, only that she died fairly shortly after Stacy was born and that Stacey inherited a lot of her good looks. We also know that Eric Hauptman, Stacey's grandfather, set up the Foundation that she now heads.
My theory then, is that the fight against gene slavery is in fact rather personal for the Hauptman's-that sometime in their family history, fairly recently, one of them was a descendant of a rescued gene slave or married one.
You´re not the only one to have considered the possibility...
