Bless your heart for taking in the little guy. He has been through quite an ordeal. It just sounds as though he needs some time to adjust to his new surroundings. He may feel safe in a corner because nothing can steak up behind him. Be gentle and loving as I am sure you are, try to touch and socialize him. Once he starts feeling safe and knows he will be feed and cared for I think he will come around.

Male cats will kill kittens particularly other males. I saw this a lot when I was growing up we always separated the father from the kittens for this very reason. Hope it works out for you both.
