IMHO it's the constant brainwashing from the left to women that every girl/woman is sexually abused every day, all the time, since before puberty. Leftist women (read: teachers) hear it way more often than the reality. IMHO that puts into female teachers' minds the idea of sexual activity with minors.
Those of us who don't hear about it all the time don't think about it -- aren't tempted by it.
I never met the woman, but I did notice she's pretty young for a teacher --- not much older than the kids she molested.
That makes me think she's on of those girls who doesn't want to be an adult, would rather fool around with (or bully) other "kids" than be a responsible adult.
That's not the first woman I've seen with that attitude.
