It isn't hard to imagine someone who thought nothing of telling a lie would be easily drawn into a scheme to fix the All Valley tournament and would call off a romantic relationship for cash. Once on the dark side it is hard to make it back into the light.
The un-truths begin almost immediately with the whole black eye "fell of my bike" incident early in Karate Kid 1.
Then of course there is that bike he supposedly crashed on, a "Miyagi turbo".
We are also treated early on to a display of Daniel's rage. Quick to react, slow to think, Daniel attacked Bobby after a rough tackle during the soccer tryouts. It could have been laughed off but Daniel decided to unleash the beast.
Proof that Daniel had a gift for taking action before actually thinking things through.
In Karate Kid 2 Daniel spends his college fund to accompany Mr. Miyagi to Okinawa. A friendly gesture however what Daniel should have done would have been to stay behind to take care of Mr. Miyagi's house. Knowing that his house would be in good hands and taken care of would have calmed Mr. Miyagi's already heavy heart.
Finally, Karate Kid 3 gives us another good example of how Daniel struggled with telling the truth, always putting his desires and need for glory ahead of being honest with those around him.
