Then you don't understand that this Samaritan took his life in his hands by being in the wrong place. That is why the story is so powerful to its original hearers.
In Biblical times, the Samaritans were absolutely despised by the Jewish nations. They were seen as a mixed-blood race resulting from the inter-marriages between northern kingdom exiles and the Gentiles that had been brought into the land by the Assyrians in 2 Kings 17:24. The Jews seriously believed that they were the only "pure-blooded," truly chosen people of God, and considered their Samaritan relatives as second-class citizens, at best.
More disturbing, the Samaritans were seen as spiritual half-breeds, something to be reviled. Their Bible consisted of the five books of Moses (the Pentateuch) only, and they believed that Mount Gerizim was the mountain on which Moses had commanded that an altar be built (Deuteronomy 27:4-6). The Samaritans had in fact constructed a temple on Mount Gerizim (where both Abraham and Isaac had built altars according to Genesis 12:7: 33:20) in approximately 400 BC, which the Jews destroyed in 128. This did not help to bring peace between the two groups, serving rather to increase hostility.

You can't seem to grasp the story itself. This was a road between cities. It wasn't a road through a land of thieves. The Samaritan's help was cash and a free ride to the next inn. The Samaritan didn't have to fight off the marauding hordes.
"That is why the story is so powerful to its original hearers.
No, it was putting up the cash that was. If you think it's so important, then you should put up the cash to make sure these climbers have enough funds to cover more manpower and equipment. Don't lay that on other folks. Cough up the cash yourself.
