Hello
I agree that there is a strong possibility that Luke 16:19-31 is a parable.
First, as my study notes put it, the main intent of this parable is to call those with a godless view of wealth and righteousness to repent and help others with their money.
Luke 16:14 Now the Pharisees, who were lovers of money, also heard all these things, and they derided Him.
Second, according to my study notes, to a Jew Abraham's bosom suggests the honored place in Paradise, that is, the beggar received a special welcome in heaven and was seated besides Abraham.
However,
In Luke 16:26, the reference to a great gulf, that is, a firmament, indicates that this is not merely a parable, in my opinion.

Now does this mean Hades is a place of torment. No. Hades simply means the grave. In my honest opinion, Jesus was symbolically referring to the lake of fire, a spiritual location consisting of a lake and at the bottom of the lake, a special prison.
