I do think that a person making bad choices in life that end in destruction is not someone I'd want to name a child after when there are plenty of people who have accomplished many things that didn't choose suicide or drugs. To me it does matter in cases like that. Amazing accomplishments in some people's eyes don't in and of themselves justify bad choices that lead to destruction... That said, if one must, Kurt on a boy would be a much better choice than Cobain on anybody. If that were inflicted on me, I'd change my name.
