Why does Paul behave like a jerk sometimes?

I think it's because of his brother, he wants to be better then him and prove that he is a good trainer. His mind tells him to be strong and doesn't understand to hiển thị tình yêu for something. Then Ash showed up and he saw how he treats his Pokemon, bạn can tell he's confused bởi his and hates it. He doesn't understand that hiển thị tình yêu for your Pokemon it the best thing to do. But at the end, he starts to change.

I guess he is a jerk because he is a jerk! Right?

He's probably a jerk because of Ash, I mean Ash can get on peoples nerves sometimes.
