I would say that it's probably normal in my opinion.
It's kinda as if someone would kill Mrs. Merkel or 50 cent or if they just die by natural causes, I personally would not care.
Maybe be sad for a couple of minutes but generally I wouldn't care.
The same thing was with that one polish politician Miroslaw Kaczynski who died in a plain crash in Russia or something like that.
I saw many polish individuals being sad about that, some where crying or even stopping in the middle of the road and honking but I didn't gave a shit. I just walked around with my earphones, blasted through sidewalks when there were no pedestrians on it and continued living my life.
I know that there is a law in a certain state in the US, where (for example) if someone dies and there is a funeral, you stop for a minute (or something like that) to "pay respect to the family members/friends/ etc. of that dead person" and this might sound like I'm an asshole but I didn't stop to pray or anything like that. I stopped because I had an Visa, I was driving a rental car and I wasn't a US citizen. I would have a lot of unnecessary crap to do if I would get ticketed by some random cop who would just wait till someone breaks this law and it wouldn't probably matter that I didn't knew about this law.
In the end I just stopped, said to myself something like "Hope you have a great time in the afterlife" and continued driving.
In the end let's just say that we're humans and everyone deals differently with death (or in this matter, even suicide)
