No... no one needs any specific person in their life. As has been mentioned multiple times in this thread in response to tr4nce, that sort of thinking is what makes the cycle of abusive behavior continue.
You wouldn't say something like that to a abused spouse in a relationship, a parent shouldn't be an exception just because they bothered to have sex and get pregnant.
Additionally that mentality is sort of rude to people who can't/don't have their mother in their lives due to circumstances beyond their control. What's going to happen to those people exactly, if they NEED a mother in their lives?
