There is nothing to factor in here.
It was a 14 year old skank who didn't protect herself well enough, got pregnant, didn't want anyone to know, and thought she could get away with killing it and disposing of it before anyone could find out about it.
I guarantee you the bitch was totally sane and was just afraid of what would happen if she told her parents about it.
You've been owned, please take your excuses elsewhere.
This is another good reason that her sanity at the time of termination should be called in to question.
