It is never explained in the story why Mario would want to defeat his own brother. Mario even comes back later as Plane Mario to stop Luigi.

It's weird how instead of Mario hanging out with Peach, it's Luigi, just like everything in this game, it is never explained. It is also never known what they're relationship status is after the ending.

Bowser
Bowser has always been a lifelong enemy of Mario & Luigi, so it's easy to understand why Bowser is going after him and the princess.
