Her child was born to a man with no money or title to his name. The chances of Luca having a decent life would’ve been slim to none in their society. Plus, Ines wasn’t in her right mind when she killed her child. Not only was she dealing with the grief of her murdered husband, she was terrified that she’d end up in a similar situation to her previous life. Was it right? Ofc it wasn’t and Ines has suffered so much guilt and trauma from killing her child.
If I'm not remembering wrong, after Emiliano was killed and Ines was taken back to her family home
Ines' father ordered Luciano to get rid of the child..Ines probably killed the child after hearing that. Don't know if the order entailed killing the child or giving it up to someone else but Ines also possibly imagined the worst possible and chose rather to kill the child herself instead of letting it live a tragic life.
Why did Ines kill her child? If the soldiers were not ordered to kill them right away, I doubt they would be killed later on. Even if taken from her they might have lived a decent life far away. Her actions seem selfish and irresponsible to me.
