Facepalm

It strikes me that Frankenstein, as a work of literature does try to teach a moral lesson.

To me, it feels wrongheaded to take the lesson "Hey, maybe if you're a being born of ultimate neglect, maybe don't do any vengeful murders" from this work.

"If you're going to make a person, which is a thing people do all the time, it is your responsibility to not neglect or abuse them" is probably closer to the truth.
