Is there any evidence in the manga/Japanese version that Yami Bakura abuses his host?
Not really. There are two instances where Yami Bakura harms the body he’s residing in in the manga, once in the Monster World arc, and once in the Battle City arc. In the Monster World arc, he impales his hand on one of the towers of the castle because Bakura had been controlling it to help Yuugi and everyone fight his yami. In Battle City, he plunges a knife into his arm as answer to Malik’s question if he will work with him or not, then retreats back into the Ring telling Malik he can ‘borrow his host for a while.’ There it seem his aim is not so much to abuse Bakura, as it is to use his pain to further his goals.
