Judeo-Christian ethics: slavery is ok and you should be smiting your neighbor for not keeping Sabbath.
American ethics: Slavery is amoral, vigilantism is illegal and people are free to practice their religion or no religion at all.
Judeo Christian ethics evolved and stated slavery to be immoral in the 1860s..
How do Judeo Christian ethics evolve?
Did the Bible change in the 1860's?
Jews and Christians in the Western World stopped slavery based on evolving ethics.
Did the Bible for Jews and Christians change? Did the words in the Bible change? How was slavery 'ethical' according to the Bible prior to 1860 but not 'ethical' after 1860?
And btw- Jews had essentially no political power in 'the Western World' to stop the slave trade.
The most notable debate
[157] was between Rabbi
Morris Jacob Raphall, who defended slavery as it was practiced in the South because slavery was endorsed by the Bible, and rabbi
David Einhorn who opposed its current form.
[158] However, there were not many Jews in the South, and Jews accounted for only 1.25% of all Southern slave owners.
[13] In 1861, Raphall published his views in a treatise called "The Bible View of Slavery".
[159] Raphall, and other pro-slavery rabbis such as
Isaac Leeser and J. M. Michelbacher (both of Virginia), used the
Tanakh (Jewish Bible) to support their arguments.
[160]
Abolitionist rabbis, including Einhorn and
Michael Heilprin, concerned that Raphall's position would be seen as the official policy of American Judaism, vigorously rebutted his arguments, and argued that slavery – as practiced in the South – was immoral and not endorsed by Judaism.

Ken Yellis, writing in
The Forward, has suggested that "the majority of American Jews were mute on the subject, perhaps because they dreaded its tremendous corrosive power. Prior to 1861, there are virtually no instances of rabbinical sermons on slavery, probably due to fear that the controversy would trigger a sectional conflict in which Jewish families would be arrayed on opposite sides. ... America’s largest Jewish community, New York’s Jews were overwhelmingly pro-southern, pro-slavery, and anti-Lincoln in the early years of the war." However, as the war progressed, "and the North’s military victories mounted, feelings began to shift toward
... the Union and eventually, emancipation."[162]
