Really? That's genuinely how you feel? I thought you'd be upset, even angry with me for my previous comment. But, you absolutely blind-sided me with your response.
You're just assuming they didn't care about their Lives. Many of them absolutely do. But due to horrific addictions or horrific mental illnesses for which they literally can't get any treatment for in America, they're stuck being homeless. Doesn't mean they don't care. Everyone has a basic human right to their own bodies. Unless a person signed a waiver while alive, signed the back of their driver's license, or the family who claimed the body, then said, "We know he'd want to have his body used for medical research," then there's a huge problem.... That person, for personal or religious reasons, might not want their body cut up or dissected for any cause/justification another person could come up with. Just because they're Homeless, doesn't mean their rights get taken away.
You have valid concerns, but for a homeless person with no relatives, no driver's license organ donor question, and no idea if they cared about their body after death (and there is not a lot of evidence in the extreme cases that they care about their lives looking at how they live--you just assumed the opposite that they do based on your personal feelings)....I honestly do not see much difference in their being cremated or used respectfully first as a cadaver, after which they are cremated.
You make it seem like they are somehow being desecrated or disrespected as a cadaver which I don't agree with.
