I need advice for a super aggressive cat?

I rescued Minette when she was 2 weeks old. I tube fed her and made her go to the bathroom with a rag so I really "did" love this stupid cat. This cats hates everything. She doesn't want me to touch her, play with her, pet her.. she is just a terrible animal! She just turned a year old and is very content just be left alone and fed. She will sleep on the bed as long as im not near her. I have two other cats whom are sweet as can be. No behavioral problems. I know Minette came from a feral colony so idk if this is just the way she is. Ive tried ignoring her but she only likes it even more. She hates everyone who visits me too. This friday I have the day off and am seriously thinking hard about having her put down. Im just tired of having an animal like this in my home. She has been fixed and up to date on her shots and really healthy so I know her anger is not from pain. My home is 1500sq ft so just me and 3 cats is more then plenty of room. Any last advice would be nice. I have cat toys, scratching posts, kitty jungle gyms (the one in my den goes all the way to the ceiling). Im just really disappointed in this animal. I have never had something that I fed and take care of treat me this way.
