These people did it to themselves by not figuring out what's required to do what they intend to do.
What happened here was completely preventable by the people it happened to. It's also in the fucking news and posted anywhere you go to make sure you know what you're doing.
Homelessness is a completely different thing, nothing at all like what happened here.
Unless you're saying homeless people are homeless by their own doing, like these people are dead by their own doing?
