I'm encouraging you to post some texts you've appreciated. Here is some I've enjoyed reading:
From The Bad Seed by William March
Good people are rarely suspiciopus: they cannot imagine others doing the things they themselves are incapable of doing; usually they accept the undramatic solution as the correct one, and let matters rest there. Then too, the normal are inclined to visualize the psycopath as one who's as monstrous in appearance as he is in mind, which is about as far from the truth as one could well get... These monsters of real life usually looked and behaved in a more normal matter than their actual normal brothers and sisters; they presented a more convincing piture of virtue than cirtue presented of itself - just as the wax rosebud or the plastic peach seemed more perfected to the eye, more than the imperfect original from which it had been modelled.
From an essay signed "A psychopath in prison".
He will choose you, disarm you with his words, and control you with his presence. He will delight you with his wit and his plans. He will show you a good time, but you will always get the bill. He will smile and deceive you, and he will scare you with his eyes. And whn he is through with you, and he will be through with you, he will desert you and take with him your innocence and your pride. You will be left much sadder but not a lot wiser, and for aa long time you will wonder what happened and what you did wrong. And if another of his kind comes knocking at your door, will you open it?
From an interview with a psycopath doing time for kidnapping, rape and extortion.
Do I care about other people? That's a tough one. But, yeah, I guess I really do ... But I don't let my feelings get in the way ... I mean, I'm as warm and caring as the next guy, but lets face it, everyone's trying to screw you ... You've got to look after yourself, park your feelings. Say you need something, or someone messes with you ... Maybe tries to rip you of ... You take care of it ... Do what ever needs to be done ... Do I feel bad if have to hurt someone? Yeah, sometimes. But motsly, it's like ... uh ... [laughs] ... How did you feel the last time you squashed a bug?
From The Miser 1668
People can be induced to swallow anything, provided it is sufficiently seasoned with praise.
