It's... complicated. Ouma-kun... and Momota-kun, ultimately... were trying to create an unsolvable murder. One where even Monokuma didn't know who the culprit was. The idea was, if we voted on a culprit, and Monokuma agreed we were right, and it turned out we were wrong, or vice-versa... it would invalidate the game, since even the one running it didn't have all the answers.

But... I figured out that was what they were trying to do a little too late. I'd already figured out the trick they'd arranged, and Monokuma was willing to believe I was right. So... I had to convince everyone that everything I'd said was wrong.
