Not every slave kept in Africa was killed in sacrifice. Most just toiled.
Not every African slave-dealing king kingdom practiced human sacrifice.
The life expectancy of a slave in a European run sugar plantation was 3 years. They were worked to death as in galley ships and salt mines.
Deaths on board a slave ship were ten percent on the low end, usually higher.

Much higher if they didn’t go.
I do think near 100%
By sacrifice or worked to death.

This is a separate issue. I’ve heard similar things as well. I’m not addressing that one way or the other. It seems consistent with numbers to North America vs Caribbean and South America.
Just discussing these things is difficult because people can mistakenly take such analyses as justifying slavery or something similar because it’s such a visceral issue.
