I'm a creep. I'm sorry
Is it just me, or is committing public seppuku like this really necessary?  If what he did was illegal, he should face prosecution.  If he's compelled to apologize and admit his guilt, he should reach out to the people he actually wronged.  This kind of public self-flagellation ("I'm such a creep. Please forgive me, world.") feels really over the top, phony, and symbolic.
