It is ridiculous that people would think that he would burn her.
Yes...and no.
As I stated in my post, Judaism itself has no consensus on what exactly happened to Seila, Jeptha's daughter.
But that may be the precise point.
Hebrew writing is more complicated and complex than previously thought or imagined by the scholars of the 1800s who developed some of the first critical practices and methods. We have since learned that if something is left open for questioning, it is generally not without purpose.
The Book of Job does this in a very blatant manner. Job spends the entire book asking why is he having to suffer, begging to hear the answer from God. When God does reply, the answer is essentially: "You tell me, if you're so smart!" In other words, why claim that something is broken if you didn't make it in the first place--it might be working exactly as designed. Just because you don't like it doesn't mean it needs fixing.
The same type of story-telling might be employed here as well. It's not about the daughter. It's about Jeptha and his vow, and what we can learn from it--namely doing stupid things from thinking we are "all that and a bag of chips," as it is often said.
We often think we know it all and we are big stuff, and because of pride we get stupid--and it costs lives...even our own.
The story is not historical, so arguing over the details is falling into the very trap that the story warns about, namely thinking you can know it all.
The Watchtower tries to make it sound a certain way since they believe in a supernatural deity, a personal God that is righteous and would never allow or accept human sacrifice. They also believe that the Bible is a historical document. If it isn't, then their religion falls apart. So they argue for ways to make it sound reasonable.
I promise you that the Jewish world knows the story is composed of folklore, legend and myth. Even if some of the elements may have kernels of history, the story is a legend. Nobody could die falling apart piece by piece by piece and be buried in various towns and cities until there was nothing left of them. The reason for this death is to imply that Jeptha cut up Seila in this manner and God had repaid him in the same way. This is mythological.
It doesn't matter what happened to the daughter. Stories in the Biblical narrative are about YOU. What does this prevent you from acting like? How does it make you better?
Are you supposed to learn from what happened to Seila? Or is it really the example of Jeptha's rash vow wherein the lesson is to be found?
If you concentrate on the daughter, you have missed everything.
