We have a planet choking to death on human pollution, babies born into squalor, people starving to death by the thousands due to inadequate resources.  I just don't give a shit about one person dying by their own hand. I'd rather they didn't do it, but if they have to, don't be a selfish prick about it.  Do you give a fuck for the train driver who runs them over and is left traumatised for their entire life? The kid who finds their body hanging in a park? The policeman investigating a strange smell from next door?  You really are a piece of work if you can claim suicide isn't the most selfish way to die.
