ADVICE recently became a single mother of 4 innocent children, pregnant with 5th

I was 30 and he Was 48 2 years ago , he was the man of my dreams. I honestly believe he was the one and I do remember always thinking this is too good to be true surely it can't be true I would often say to myself.  Shortly after we fell pregnant with my now just 1yr old (just last week)  precious little boy! The past year things had changed dramatically , I began to see a very aggressive , damanding, very one-sided , selfish and unbelievably nasty cold person forming before me. As I started looking into his past I found that he has a very violent history not only with men but with every relationship he had and is a man that is of high danger and very well known from police. I got taken out of my home one day with my children , (I assume my neighbours must have been making reports) and I was placed in protective services in witness protection. 

Turns out it was easy to find me . I've convinced him that I was to see him but he lives in his own house and I live in one the children all live with me and I know I can support them on my own as he never paid for bills and living expenses anyway. Now this is where my question concerns and I just need some advice without judgement please, 

I recently found out I'm three months pregnant with another little innocent child... I am so scared and confused and now I'm mother of five children with a dangerous Ex keeping a close watch on us which I will not be intimidated by an animal or worry about when no if he's going to do something, I wanted to know is it wrong if I continue this pregnancy?

I love my children, and the most talented smart well mannered respectful strong little individuals that I'm so proud of and inspire and teach me things each and every day! I understand my situation is not at all what I would've chose to bring a baby into this world right now but does anyone else believe the just maybe if I continue to provide love support and to protect my children that they can have a bright future?  Or am I setting them up for a life of resentment and chaos?
