About The Dark Knight (answer only if you've seen it)
It was pointed out to me that it was unlikely an absolute good guy such as Harvey Dent would turn into a murderer "just like that", even after all he's been through. He talked to his girlfriend a matter of seconds before she died, and he was permanently disfigured by being burned on one side of his face. But a counselor friend of mine says that would not be enough to prompt an abrupt change in personality, unless he was at an impressionable age, which he was not.
I say, he wasn't "the white knight" that most thought he was. Everybody has a dark side, and he already was showing the very roots of Two-Face's personality earlier in the movie. Case in point: the scene in which Harvey was flipping a coin to decide whether to shoot a suspect in the face. Sure, the coin had two identical sides at the time, but the suspect didn't know that.
What are your thoughts?
