Sorry, it is. It's the ultimate selfish move. What about his daughter, his family, his friends, his filming crew? All those people are broken because he took the quick way out.
"shut the fuck up" yeah okay I get it, it's disrespectful to say that, but it's entirely true. The dude was a genuinely good guy it seemed like, and it's fucking awful the world is deprived of that... oh hey, that's another reason it's selfish.
Should he have been forced to stay in the limelight? No, and maybe he was forced and this was his way out, which makes it all the more tragic. However, it's still a selfish act.
I'd say it's selfish when you have kids or you put yourself in a situation where others depend on you (like running a business) but otherwise not really. ---
