Blackbeard is currently cute compared to other antagonists in terms of evil...
Kaidou for example, not even 20 years of prayer were enough to stop him from killing the hero that an entire country had been waiting for.
Kaidou was already very bad even though Orochi was the Shogun, Kaidou called someone like Orochi who was an abomination "soft".
And indeed it was, since children could still play around in wano, Kaidou would however enslave everyone, old people, children, women, it didn't matter to him.
For him, cooking a member of the Whitebeard pirates, and the Roger pirates, and an heir to the Wano Oden shogunate is nothing more than a game, cooking in oil for 1 hour works. And in the end he killed Oden with a shot to his head.
He killed the Daimyos, Hyogoro's wife and his children, Oden, Toki, Kaidou started murdering everyone and the number of graves only increased.

There were also those attempts to overthrow Orochi from power mentioned by Yasue that ended in failure thanks to the overwhelming power of kaidou that transcended everything
