Forum conversations get weird and disjointed sometimes. Captain Swoop said that he had 20,000 people killed and the bodies thrown overboard and then claimed the losses on his insurance.
Brainster was saying that sounded fishy, because such a policy seemed like it might bankrupt the insurance company.
I was pointing out that perhaps Captain Swoop's description was a bit misleading, and that the insurance company, even then, probably had the means to protect themselves from deliberately damaging the goods.
It's a conversation about insurance. Insurance. No morality involved. No judgements. Just insurance. Everyone understands that the slavers are responsible for the deaths, but that wasn't really what was being discussed. A later poster provided some more details about what losses were and were not covered by insurance.
As for stature worthiness of people who lived during the era of African slavery, see my previous answers for Washington, Colston, and Lee.
