Justified in that he's a rather kooky, old man who's not up for much besides sniping whatever catches his fancy from his penthouse suite balcony. Orcus on His Throne: He spends the majority of his days in his penthouse suite while his minions, Mister Burke and Chief Gustavo, take care of any actual problems he has.The Mean Brit: He's got Very Evil karma, though when speaking with him personally he comes across as rather affable.Make It Look Like an Accident: If Roy Phillips is allowed to move in, Tenpenny will suffer from a mysterious "accident" shortly after a disagreement with Roy.
Kick the Son of a Bitch: If you kill him, you get Good Karma.
It hardly excuses his other actions, but why he's marked as worse than horrifically evil people like Jabsco and Roy Philips, who are unrepentant mass-murders, is a mystery, but its implied that it is more due to his past deeds and legacy. He wanted Burke to evacuate Megaton's population before flattening it, and even his Ghoul prejudice is pretty mild considering he's willing to let them in and live in the tower if they behave themselves.
Informed Flaw: While he's certainly a bastard, he doesn't really merit his Very Evil Karma ranking. If you convince him to let the ghouls move in peacefully, he'll say flat out that he wouldn't mind hunting down any who cause problems. Hunting the Most Dangerous Game: His "Wasteland Safari" where he fires randomly off into the Wasteland, implies this. Unfortunately, Burke was willing to ignore this and let everyone die anyway. Even Evil Has Standards: Granted, wanting to see Megaton blown up is a horribly dick move ( because it was marring his view), but at least he had the decency to ask Burke to evacuate people before the deed was done. (Also he seems to really enjoy Susan's company from time to time.) try not to think too hard about what he probably did with her. Dirty Old Man: He used to own Mei Wong as a slave.
Cloud Cuckoolander: On account of being, well, old. However, when you actually meet him in person, he turns out to be pretty much just a crazy old man who's not actively evil, just selfish and ignorant of the harm he's doing. Arc Villain: He's the antagonist in three of the game's major side-quests, and (up until President Eden makes his move) is probably the most well-known individual antagonist in the Capital Wasteland. Affably Evil: He's a very polite and charming old man, who likes to hold conversations with you and will even give you 500 caps if you negotiate a peaceful solution concerning the ghouls. He spends his days bored and "on safari", which means sniping things from the top of his grand tower. The owner of the tower and all-around Jerkass. "Well done, Mister Burke! What a grand display of fireworks! I almost wish there was another nuke we could detonate!"
