Honestly, I love the way how House is written, because he's quite clearly a Narcissist, but most players will take his explanations as to why he does the things he does at completely face value, not realising how genuinely unsettling the way House acts is. Like most of his explanations as to why he's doing the right thing come down to "I'm impervious to corrupting ambitions for money and power, you can see by my actions that I'm solely interested in human progress", "With my help mankind can be on the moon in 50 years", and it's like everyone takes that to be 100% true, but this is literally a man who wrote his own obituary calling himself the only hope for humanity. All of his arguements basically amount to him being a singular great figure, and everyone else being more corruptable than him. He's implied to have literally dated an actress SOLELY so he could write a code to virtually simulate her behaviour in the event of an apocalypse, he literally created a massive ghetto for any of the Vegas locals that he couldn't intergrate in to his own society. The game repeatedly shows you how blatantly abusive House is, and how he's willing to basically step over and manipulate anyone towards his own ends. The great thing about New Vegas is that most players don't really examine it much beyond "What do these factions believe in?" and don't realise that there are multiple additional levels of subtlety: the people who tell you what they stand for and what they represent are not reliable narrators(Arcade literally points out that Caesar has basically abused Hegelian philosophy to feed his own megalomania about being the single most important figure in history), and a lot of the subterfuge done in the Mojave requires a lot of critical thought to realise what's actually going on.
