These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Fernando VIII from Gardener of Gratitude. He expresses extremely sexist views against women, believing them to be nothing but sex objects (parodying his obvious Bishounen appearance). He also killed at least three people in cold blood - his own parents and an elderly man - for the purpose of obtaining information to advance his own goals. Eventually, he gains control of one of the Olympus Mons and begins destroying his city, explicitly getting off to the suffering he's inflicting.
Ho Yay: In Chapter 31, Nando gets cornered by a drunk casino patron who mistakes him for a woman, then looks him over for valuables (and maybe something else). Topped with this pair of Double Entendres:
Nando: I have nothing of any interest to you gentlemen. Please, let's work something out here...
Moral Event Horizon: Paul gets his when he orders his Magmortar and Electivire to attack his Kangaskhan even though it's already wounded, because it didn't battle well enough. Not cool, man.
Dr. Yung's could be said to have come at any number of places, but when he viciously beats Maria in Chapter 32 for directing her still-loyal followers to disobey him, you know he definitely reached it.
Narm Charm: Looker's speech patterns resemble those of Yoda
