But you yourself said; mutants who have had bad experiences with humans won't like the idea of another human, even an innocent one, wandering about the island? Even if his mother's a mutant, how can we be sure Shogo is truly 'trust-worthy' in this context? I'm curious to hear your reasoning?
And, yes, that is a good point, the council would consider the mutant's survivability in regards to their human carers: But what if their survivability can be ensured without them? What if it's simply a case of, like in the case of many developmental disorders, they would survive without them but would not be happy? They would not thrive, in a sense?
