It was a selfish act. No question about it. Bourdain left an 11 year old daughter. He did so because he wanted to end his own life far more than he cared about who would care for her. Or what effect his death would have on her. And she is a young, impressionable child, who has her whole life in front of her. He didn't give a damn about that, or her. If that doesn't define the textbook definition of selfish, then I don't know what does.
His death meant more to him than anyone else who was dependent on him. Again, that's about as selfish as you can get, no matter how you look at it. Especially when it's a young child. It's much the same with the alcoholic. They see what's happening to their lives, jobs, finances, families, and marriages. But they don't care. Because they would rather drink anyway. It's easier than getting the help they know they need to beat it. Just like the depressed suicidal person does. It's easier to 86 themselves and be done with it. These people toy with the idea of suicide for months. Some for years. Just like the alcoholic drinks. This process doesn't start on Monday, and end on Tuesday.
You can make excuses on their behalf, and feel sorry for them if you want to. Or if it helps make you feel better about yourself. But the result is the same regardless. They took what was for them, the easy way out. Death by suicide, and or constant drunkenness through alcoholism. And by doing it they left a path of emotional destruction their families and children have to clean up. Many don't. It effects their lives in a negative way for decades to come. While this may sound harsh, I'm certainly not going to waste my time feeling sorry for anyone selfish enough to do that.
He had also made the comment he would have liked to have been chosen to cook for President Trump...... So he could poison him. People who make idiotic comments like that I just can't feel sorry for.
