Nikaah & Marriage Issues

Q: I have a question regarding milk parents. 

I was conceived by my biological parents with the intention of being adopted by my aunty (fathers sister) as she hadn’t had any children with her husband for 11 years. 

When I was born, I was adopted and grew up in another city with my (new) milk parents. From small I was told about my adoption so it wasn’t something shocking to me. 

I grew up knowing my siblings and visiting my biological parents often, but my milk parents were like my real/main parents and my biological were like my aunty and uncle. 

Now that I’m older and married and my siblings are also older and married and I’m staying in the town I grew up with my biological parents. I hadn’t been there as much and made the khidmat owed to my biological parents. 

My biological parents said multiple times that I should treat my milk parents as my real ones and that they (the biological ones) hold no haq over me. I asked my shaikh what to do and he says that shariah is above everything and that their words or emotions don’t govern what the actual rights to them are. 

So my question is who holds more right over me, the milk parents who raised me or the biological parents who bore me? 

When it comes to khidmat or instruction, who holds more weight? 

And lastly, if they excuse me from khidmat what does it mean?

Q: My sister was 6 months pregnant when a scan showed the baby was not growing well. The doctor said this is a case that the baby will not grow properly. The baby has no lungs and is just alive on the mothers breath. The doctor said if you wait for normal delivery there will be some risks in the delivery and also to the mother's health. The doctor advised to terminate the baby. And we accepted the advice. The baby was delivered and in a few hours died. Sometimes I feel it was not the right thing we done. Maybe if she delivered on her own time then the baby would be alive. 

What is the Islamic ruling? Was what we done a serious sin? If yes, is there a chance of Allah's forgiveness?
