If you think in positive way, your father being chase out is a good option and he stay with you. Of course I believe that you are capable enough to take care of your father right. So since that ANIMAL already taking the step that assist you all to live free, just accept it.

So sorry to hear that he actually con his own blood stuff, as you can say, he didn't got any job and stay like a BOSS in the house for almost 34years without doing anything which mean he is old + stupid in term of knowledge and wisdom. No knowledge, No job, how could he survive with a house which is just 400k?How long can he live up with that?Believe me, in future, he surely will hit the wall hard and maybe one day, he will bend his knee in front you and ask you to help him for living.

Believe in KARMA, do what your best to take care your parents. Just assume that this ANIMAL wasn't exist.

obviously its internal family matter lar ~
But he is here to share his thought and hope someone to give opinion, of coz with support. If everything also need to do it internally and externally, then don't live in society pls, go live in the jungle.
