Debate Competition

I often see myself agreeing with both sides of a debate but then I wonder.. are some responses mostly a result of one person wanting to be the "right" one, and wanting to win and wrong the other, defending what they initially believed in?
Could this be either good or bad, either invoking good serious thought put into the discussion or borderline untruthful statements made to accommodate the person’s position?

It really depends on the situation. Look around here and see all the debates going on, and I mean actual debates, and then look at the stupid arguments. The difference is usually the person who is calmly debating typically thinks they are "right" but doesn’t let it get to their heads, while the people arguing typically are extremely high on themselves. In the situations that are true debates, each party uses the previously laid out thoughts with clear evidence to back it up, while the people arguing use logical thoughts until they feel that they need more. These people always pull facts out of nowhere and after all of two minutes they break down and resort to name calling to try and make the other person mad enough to leave, thereby admitting the other was correct.
