[Dragon Ball]Why did Piccolo decide to fight Goku through the tournament?

Why did Piccolo decide to join the tournament? To fight Goku? He would probably challenge Goku outside the tournament anyways.

Piccolo was portrayed as not being as dangerous as King Piccolo but he was still pretty evil. It’s hard to think that he’d limit himself with rules to fight.

Is there something I’m forgetting?

He wanted a spectacle.  To beat the man who killed his father in front of a crowd, revealing who he was (odd that he was 'hiding' his identity, as similar as he looked to King Piccolo) and declaring the start of his reign before an audience that included nearly anyone else that might have considered challenging him.

I'd say he was more dangerous than King Piccolo, as he was fighting a young adult Goku, nearly full grown and with several years more experience than the kid that killed his father.
