I agree most with silmaril. It's a bad comparison.
Evil and Good aren't absolutes. They are relative. Without good, you cannot measure evil. Without evil, you cannot measure good.
Actually, he is misusing terminology. The correct words are Cold and "Hot" which are qualitative descriptors for a measure of Heat. "The Sun is Hot." "The Antarctic is Cold."
Besides, to follow his analogy to its logical extents, people can only withstand a certain range of temperatures (or heat). So that would mean humans can only do so much good, or so much evil. To far to either extreme, and you would die.
Ok, done rambling. Hope that makes some kind of sense.
Flaw in the logic....
