Questions on the plot

Should I make Kurumi become a full pledged villain, intervening at the mha story's main events involving villains (USJ arc, Hero Killer arc, Forest training camp arc ect..) or make her sorta a villain and enter UA to follow the MCs of MHA along all the arcs. If kurumi chooses the villain arc, the story would be more interesting and unique with her becoming one of the most feared villain. If she enters UA, there would be more screen time for the MCs of MHA. What route should I choose? Write in the comments.
