I would go back to the work so that I am never in a position to even consider their settlement... and spend some effort in fixing the core issues that prevents such accidents in the future by bringing it out to the public... maybe also work for companies that are in the business of fixing those issues... not with anger or hatred which can lead to non-solutions which may do even bigger harm but with compassion. Is it possible for you to work for that company so that you can try to fix it from the inside? Ideally, I would do that, given that I could get over the grief and somehow become enlightened... but then it is easy to imagine being enlightened when it comes to problems one is not facing themself. In reality, however, I would live a miserable depressed life stuck in past trauma waiting for inevitable end of my suffering, like I do with the problems I personally have in my life. I have come to learn that Vipassana meditation, Peter A. Levine's trauma therapy work, Ayuaschia and a whole lot of spiritual and other practices and therapies are supposed to help one get out of the rut and move on... but I have yet to find anything or have access, or have ability or will to find anything that has worked for me.
