Abusive parent

Q: What are the obligations of a child to a parent who has emotionally abused their children and refuses to take responsibility or pay any bills relating to the children and household expenses? If this parent keeps late hours and is difficult to live with, can the children move out or make him move out (with the help of other relatives)? And will my lack of affection toward this parent ( my father) be a sin? I am afraid of him testifying against me on judgment day, but to be honest I feel life would be easier without him in my life. Am I evil for feeling this way? Please advise as I am very distressed about this.

Dolphins

Q: I would like to know what is the ruling regarding dolphins. I know that it is regarded as the pig of the ocean, however why is this so and ‎would the same rules and prohibitions regarding pigs also apply to dolphins. Would it be acceptable to attend dolphin shows or touch it etc.

Abortion

Q: I have been married for more than six years now and have two kids of age 4 years and 3 years. Handling 2 kids has become very tedious for us as we don't have anyone to support us (as we live in the city for my job and parents are back in town) and both the kids don't eat well and are quite trouble makers. So we had many sleepless nights and late mornings. Managing them has become so tough that we are losing cool on small things and getting into fight frequently. Yesterday we came to know that my wife is pregnant again and we are in confusion on how to re-act to this. My wife thinks that it is best to avoid it now considering the current situation and plan it later on for the third child. She thinks by using tablets we can do this. I am not sure how to react to this!
