Nadia: Can you imagine a society without outcasts?.
Wan-Sze: Oh yes. If brain washing and mental manipulation techniques are perfected, it won't be necessary to "outcast" anyone.
Kasim: At that point I fear that we'll all be outcasts: humans are not meant to have that much power.
Will: Yeah. Too much power inevitably corrupts and a certain level of anarchy is ideal.
