They wont suffer in life. Most of them will be brushed under the carpet, and history will forget them. That doesnt sound like much of a consequence, but these are people who had the chance to leave a lasting legacy for being great, but in 100 years realistically only a small handful will enter the history books and it will be as villains.

Not even a "good" villain like Hitler, who despite the evil had a good shot at conquering the world.

If I had a chance to be remembered as a great leader, or a super philanthropist, or being Iron Man, or even a supervillain, and instead my legacy is to be completely forgotten by the world at large and my existence actively attempted to be covered up by anyone I ever had dealings with, I'd be a bit mortally upset.

Its not much to hang onto, and we can still hope and pray they face justice in life, and we can hope for a morality-based afterlife so they may face justice in death, but they will at least face justice in the history books.
