True, but his point about missing information that could lead to the root cause is very valid. In some cases addressing the root cause is the only way to really prevent death.
and "he died of being homeless"? why was he homeless? because society was so cruel and uncaring? sure, he had nothing to do with it himself.
the other comment is right, this path inevitably leads to judgment and speculation.
Or, from a different epistemological viewpoint, the root cause of everything is God’s will.
Ascribing importance to intermediate causes is highly subjective, even assuming they can be reliably determined.
Only if you think that the laws of physics are deterministic, I guess.
