Bit of a masochist aren't we? I mean I guess you have a point... where would we be in our scientific advancements if we never indulged in the torture of living things? All joking aside, I genuinely feel bad for the drifters ghost. He treats her like garbage and after seeing such treatment I've decided to start a ghost protection agency for mistreated and battered ghosts... So I'm afraid that if you take action to harm these intelligent beings, be it for science or otherwise, I will be forced to introduce you to the business end of le monarque. Ye be warned.
