There is more to this story. 18 year old and pregnant means she most likely had already her health and health of baby abandoned by the pimp as a means to bully her into an abortion or death of her own.
This was a situation beyond her choice.
If that were the case she may have felt so, but that wouldn’t be true even then.
It is never beyond your/our choice.
That’s just an excuse to throw another baby on the funeral pyre of Child Sacrifice to the god of selfishness.
In other words, murder.
