well, part of it was the fact that she was going to end up in the same position as those girls because she doesn't have the physical strength or any sort of training to go up against them, and once she throws the pail at them, she's out of weapons.

So instead of going 'hey, Mori, teach her how to to defend herself' they punish her and act like SHE own the host club an apology? Because her feeling about the whole situation are so much less important than theirs.

I also don't think Kyouya would have actually raped her.

Just because he didn't follow through on his threat doesn't make it ANY better that he still made it.
