I don't mean literally, because we all know his sister Jania did this. What I believe is that when Jacen altered the future, he also altered the chances of him living. He changed the future, so the present would change as well. We know that the celestial's were in charge of this current, so perhaps they were not so happy that someone altered the future, and decided that Jacen should pay for it. We know that his actions was like a domino effect that eventually released abeloth. Any thoughts on this idea?
