So at the moment I'm currently rereading My Hero Academia from the beginning, and I'm on chapter 26 again. Now I may've already mentioned this, but something got me thinking once I got to this page:
He does have one. Provoking Deku to have an all out fight with him. Ochako is his first friend, so it makes sense to target her.
That's actually what I was thinking too, it's the perfect motivation for Deku to go all out against Bakugou in the final round.
