Oh, that sucks to watch, huh?! So sad...
I don't think the world is happy to support him - I don't think the world knows what else to do. We all have rights as human beings, and my experiences so far is as long as those rights don't infringe on someone else's rights (legally speaking), we are free to self destruct in whatever way we choose.
We are in a deep freeze in my state - record low temps - and it is a scramble to try to offer the homeless (the majority of which have some kind of behavioral disorder) a warm place to be right now so they don't freeze to death. So in my neck of the woods, the community is trying to do something but there isn't much that can be done without consent, ya know?
