I think the psychology way to judge her is more relevant, it shows us that Ms. S is a maniac, or a person have mental illness, which will make us think that the cause of her strange way of judging things, is she evil or pitiful?

Humanity

                        Humanity

Every rose has its thorn,

Do not think they’re easy to be torn.

Angels don't belongs in human world,

Only demons can walk through this door.

Be careful of the person that wants to be your friend,

Because that could be the day you will say hello to hell.
