Could you please pyschoyze this person's mental health for me ?

I have also come across such characters in my life. It is very difficult. Our mood will get spoiled. It is better that we concentrate on our own areas. I believe fully whatever you have stated though it is long. Other than prayer nothing can be done by humans like us. I do not know why it happens in only few selected families. It is not in every house. It may be one in lakh or so.
