My husband has a violent gene. Should I keep my unborn baby?

My husband has a dangerous condition - Jacob's syndrome, a rare genetic disorder where men carry an extra Y chromosome (XYY). But it's not just the genetics - he has an uncontrollable rage that turns him into a monster. It all started when I saved his life. After that, he became obsessed with me, relentlessly pursuing me for three years. He deliberately ran his car into my childhood sweetheart, leaving him permanently disabled. Then he threatened to kill my entire family unless I married him. For seven years after our marriage, his controlling behavior became pathological. He even had a tracking chip implanted in my body and completely controlled my freedom. Yet at the same time, he showered me with endless love and catered to my every wish. When my mother-in-law pointed her finger at me while speaking, he snapped it without hesitation. When my sister-in-law's child disturbed my afternoon nap, he threw them both out of the house and severed all family ties. I refused to have a child, terrified of what darkness might be passed down, so he invested his entire fortune into developing cutting-edge genetic screening technology, making it possible for me to conceive a healthy baby. But on the very day I discovered I was pregnant... My mother-in-law stormed into our home with a group of people, accusing me of having an affair and carrying another man's child. They beat me until I lost the baby. As I lay there barely clinging to life, my husband finally arrived. My mother-in-law thrust a doctored video in his face and said, "Troy! Your wife had an affair and got pregnant with another man's child. Look, here's the proof!"
