a parable that fits in all facets of application,
As you see it.
Also, according to JW doctrine, God is not all knowing and the Jews were not destined to kill Jesus:
“Jerusalem, Jerusalem, the killer of the prophets, how often I wanted.. but you people did not want it..” So Jesus attempt would have been pointless had the Jews been predestined to kill Jesus. According to JW, they weren’t and could have repented like in Jonah and would have exclusively made up the 144,000.
