Is it normal that i don't care at all for my family?

Like the title implys, I don't care about my family. They are very selfish self centered people. My mom, her sister, my mom's mom, and my older brother. My grandmother is like 50 and she acts like a whore and a selfish little child. Oh and she gossips and she's been acting this way since my mom and my moms sister were little. She used to bring men home when my mom was younger but none of them ever touched them or anything. My mom, is sometimes a strong person but when it comes to her mom and her sister she's there carpet to walk on. Also my mom is a compulsive liar just like her parents. and a little selfish too. Her sister is a selfish house wife who has a low self esteem and likes to gossip too. My brother is a hot tempered compulsive liar too. Which me and my father blame my mother for this because of the events from our child hood. My mom used to make me and my brother lie and hide things from our father. Which I do not do anymore but my brother stuck to it. Honestly I am tired of there personalities. I'm lucky that my father has taught me better. If they were to die tomorrow I would not care. Not one bit. It may sound selfish and crude but I don't care. I have no patience for liars and selfish people. They also claim there religious. Ha! What a laugh. Mind you I'm not religious nor do I criticize people's religion but if they were Christian they wouldn't act this way. So do you see why I don't care for them? Do you think this is normal?
