Everything has an opposite-very true in the modern dualistic physics and also in the western philosophy (of plato/aristotle), was just watching V for Vendetta (again) and this conversation struck me:

[evey is released from the ‘cell’ and discovers V held her in it, and they start talking]
Eve: “You r getting back @ them for what they did to her…and u.”
V: “What was done to me created me, that is the basic principle of the Universe: A reaction will create an equal and opposing reaction.”
Evey: “ is that how u see it, like an equation?”
V: “what was done to me was monstrous.”
Evey: “and they created a monster”

and they created a monster, that is true as well.
