I think the opposite is true. He's only dangerous to those on the list as long as the list is secret. Once he releases the names he's safer than he is now. If he doesn't release them he'll probably commit the same kind of 'suicide' that Ms. Palfrey did.
Actually he is safer now. He has a couple of separate servers that he has to key into every day. If he goes 24 hours without checking into those servers the names will be automatically released. So he won’t ‘commit suicide’ as long as he has that procedure in place. After that some people will want revenge.
