Of course there is. You cannot ask dead people if they regretted the attempt but it was too late. But just going from a very high regret rate among survivors I think it’s quite safe to assume many of those who were successful would also been happy to have survived.
I’m guessing there’s a bit of survivorship bias here. People who really want to die will probably choose surer methods, and/or try again and again.
