It can't be helped. In their world morality is not so important. Well of course if it was some maid close to their master she wouldn't be abandoned like that. For example the one who served Qiuyu for her two lifes. I think their way of thinking is if it's to achieve my goal some lowly maids can be sacrificed, they are not close or anything. Just some faces in the crowd. I think it's just like that for everyone. I mean if you were to choose between someone you love and some stranger, it's obvious you would let the stranger get killed to save your loved one. Of course you would feel guilty because that person died because of you but you will just keep living. And most of all for someone of royal family like the prince, the servants are just pawns, it just logic that exist in there. We can only accept the fact they didn't gave a damn about that servant girl. Maybe they planned to make her a proper grave later on, who knows. ╮(￣▽￣)╭
I agree.
“She was just a servant. She’s probably already dead.”
Seriously?!? Once she served her purpose, discard her like garbage and not another word about her. A$$holes
