Largely, morals should be ignored - or at least taken in the context of the currect editor, not the original story's writer.

Most folk tales have no clear moral. They are generally clear to the society from which the tale comes and needn't be specificied there. However, since morals by definition are subject to the mores & religion of a specific society, they may be very different from yours or that of the current book editor.

Thus, Christian editors printing, to them, inexplicable tales (which are clearly fables and in which some effort is "rewarded" or "punished" for non-Christian (ie, inexplicable) reasons - generally squoze/adapted the tales until a Christian homily would fit it.

Make sense?

Aesop, eg, is wildly redacted. Most tales are centuries or more later and the morals have little to do with 6th century bce Greek religion or morality. Best modern translations can be surprising- not what we grew up with.

Same for what drove unpaid ex-soldiers in, let's say, 16th century Europe.
