You are ridiculous.
Your mind cannot asses the dozens of factors involved when people commit suicide let alone this case specifically. Say hello to Sarah Palin.
Dude, killing YOURSELF, is the definition of selfish. No one else is doing it, no one is forcing you too, you make the choice because you want YOUR pain to end. That's selfish. Doesn't make you a horrible person, doesn't mean addiction and depression aren't serious. Simply means that you, yourself, have chosen to kill yourself regardless of what it does to anyone else but yourself.
