I imagine Diavolo could avoid BtD if he managed to erase time right when it tried to enter his eye, but he'd absolutely have to use Epitaph in order to know the exact moment. Otherwise, Diavolo would be blown up like anyone else.

The larger problem is that BtD only reacts when someone learns Kira's identity from its host. Kira can't activate it manually and it doesn't respond to protect Kira at all. If Diavolo had no interest in learning Kira's identity and simply decided to kill anyone nearby who saw his face, Kira would either be completely screwed, or would have to undo BtD and use Killer Queen to protect himself. And obviously, Killer Queen can't stand up to King Crimson in direct combat. I'd say King Crimson's probably got this.
