She isn’t human because her DNA has been modified so as to no longer match human DNA, she is something new and different. Just like humans are not “Home Erectus”, Maddy isn’t “Homo Sapiens Sapiens”. That isn’t an issue as long as you don’t take a humancentric view, i.e. sentience and intent come first and are of greater importance.
Which is a view all my characters share funnily enough, even Miria who has a distain for deliberate mutating doesn’t have a problem with mutants themselves ( Sapiovores excluded) and will likely as not do her best to help them (by offering them free purifier
)
