In a letter to Harold Laski, Justice Oliver Wendell Holmes famously wrote:
I always say, as you know, that if my fellow citizens want to go to Hell I will help them. It’s my job.
And he meant it. Beyond such obvious examples of this philosophy, such as Buck v. Bell, where Justice Holmes upheld a law requiring the sterilization of those deemed mentally incompetent (even if there was no real evidence they were mentally incompetent), I was recently reminded of this quotation when I taught Giles v. Harris.
