Firstly, unless you plan on creating a zombie feotus, it isn't going to survive. It'll die with the mother... but then a zombie baby might go some way to explain why you think the infant would be "antisocial" and "aggressive".
Our understanding of normal human psychological development originates in the cruel experiments conducted on Rhesus monkeys by psychologist Harry Harlow in the 1960s. I strongly advise you read about these studies. The gist however is that monkeys whose mother was replaced with a metal food dispenser, whom were socially isolated for months or years at a time before first contacting other monkeys, came out severely disturbed, and some of the poor monkeys were so stressed at first contact that they died of shock.
By the late 1960s John Bowlby's research into childhood development led to the idea of Attachment Theory (for example, see article), which has since been vindicated as the best psychological theory relating to childhood psychological development. His research concluded that a child needs a close physical and emotional bond with at least one primary care giver. It doesn't much matter if that care giver is a mother, or father, or anyone else. The ideal psychological development comes about from the primary care giver showing attentive love, and close and frequent physical contact.
It has been established that hugs release hormones which induce positive emotions, and so if you want your baby to turn out as a well adjusted individual the best chances of that are from cuddling it as much as possible when young and responding quickly to its needs. Children learn by example, and if a child is loved it too will show love. It's possible for individuals to develop coping mechanisms without a primary care giver, of course, but generally being deprived of attachment has extremely negative consequences. For example, many of the children who spent their young years in orphanages in the former Soviet bloc suffered trauma and learning difficulties as teenagers and adults, even when adopted later by loving and wealthy American families.
In conclusion: a good and loving parent who is a child's primary care giver will ensure their normal psychological development, see attachment theory. Whether that care giver is a mother or father is irrelevant, what matters is the quality of the attachment and the environment they grow up in.
There is some evidence to suggest that children without a father tend to be more maladjusted than children without a mother. But I don't know enough to judge how fair that analysis is, just that it has been proposed. So your intuition may very well be completely wrong.
