Yeah that was dumb. The rationale in the book was his team was getting clobbered and he just wanted to end it on his terms, but at that moment his team was only down 160 points! They were perfectly capable of scoring ONE more goal, after which if he caught it it would go to overtime or sudden death or whatever they do in the quidditch world cup when it’s tied.
Which is also dumb because he caught the snitch, causing his team to lose the game.
