My new kitten is very vicious and mean?

I've had kittens before and NEVER experienced anything like this. I picked up a kitten today, I was weary because the first time I picked it up he immediately clawed me across the chest, but, I continued to take him home. His owners were very drunk and had many cats. I felt horrible and thought I could offer him a better place to live.The entire car ride home he meowed SO loudly and insisted to come to the front seat, so my boyfriend brought him up. I know cats don't like cars anyways and he wanted out of the crate so I let him out and he crawled behind my neck and scratched me all over. The back, the shoulders, all over he actually drew blood several times. As soon as we got back to the house he went ape again. He punctured me in the chest so I decided to trim his claws and he clawed me in the face and has been growling. I squirted him with some water and he calmed down. I am pretty sure that his previous owners got him drunk or stoned because he is wobbly and has no coordination. I don't know if I can keep this kitty, I already hate him. I want to give him a chance, but he is SO mean.
