Would a man get a woman pregnant to keep her?

This would be very unusual. Most men do not long for a child, but an abuser can become excited due to the expectation of control over more people. If this is the case, then the female must get away before she gives birth in order to avoid at putting the children at risk. The abuser will do whatever he can to keep his victim, including getting her pregnant. There are no limits, as he feels that he can not live without control. The prospect alone is maddening to him.
