Who said that giantesses have mercy?! They really don’t care how they treat other people. They think of them like little slaves.
Just see at this giantess’ bahaviour. She seems so powerful and cruel. But apparently some people like it that way. They like to be slaves without their own opinion, doing everything a giantess asks them.
I wonder why they do that… Is there some benefit? What will you say…
