Maybe I’m just face-blind or being dense but the photos from the scene of the crime look like a different dude than the ginning hostel check in guy. The jackets and backpacks are different. Although people can have multiple jackets and backpacks. We don’t see much of the shooters face but the eyebrows look different. Although, people can pluck/shave eyebrows. I guess the happy hostel guy would have come forward and been like “WTF?” and “I have an alibi” if it wasn’t him?
It doesn’t matter what he is, who he is, or what he believes. He could be a nazi from the US taliban who thinks healthcare is the devils work and wants to kill every healthcare CEO for spreading hell on earth, or any other crazy shit. People would shrug and still say he did the right thing. They hate him as a person, but the action of killing a CEO itself could galvanize people to start attacking millionaires, billionaires, wallstreet people, bankers, CEOs, etc.
